The source code is such a fun read (for the comments). I found some source code for GW-BASIC, and here are two of my favorites:
;WE COULD NOT FIT THE NUMBER INTO THE BUFFER DESPITE OUR VALIENT
;EFFORTS WE MUST POP ALL THE CHARACTERS BACK OFF THE STACK AND
;POP OFF THE BEGINNING BUFFER PRINT LOCATION AND INPUT A "%" SIGN THERE
;CONSTANTS FOR THE RANDOM NUMBER GENERATOR FOLLOW
;DO NOT CHANGE THESE WITHOUT CONSULTING KNUTH VOL 2
;CHAPTER 3 FIRST
Fun fact, GW-BASIC was a descendant of the original Altair BASIC. The "Translation created 10-Feb-83" headers on each source file refer to tooling Microsoft had that automatically translated the 8080 assembly to 8086 (it shouldn't be taken as a build date since they were manually modified after that point). Besides GW-BASIC, source code for the 6502 and 6809 rewrites of Microsoft BASIC were available up to this point (see https://www.pagetable.com/?p=774 and https://github.com/davidlinsley/DragonBasic) but I believe this is the first public release of the original 8080 BASIC code.
Eclipse has had an integrated spell-checker, which I believe is on by default for most file types, for like approximately forever. Now maybe everybody turns it off, but I gotta imagine there are some people who like it and keep it on.
Emacs has the ability to do spellcheck inline, both as a run through the buffer (old-school style) and as an as-you-type live feature. That said, I do most of my coding in JetBrains IDEs these days.
For Vim/Neovim users, there is one built in that is pretty good, and once you've added frequent custom words to the dictionary it is great. You can turn it on with `:set spell` or off with `:set nospell`. Add custom words by pressing `zg` on the target word:
I have this in my vimrc file so it's on by default for certain file types:
" Turn on spellcheck for certain filetypes and word completion.
" words can be added to the dict by pressing 'zg' with cursor on word.
autocmd Filetype markdown setlocal spell
autocmd Filetype gitcommit setlocal spell
set complete+=kspell
" Don't highlight in red an underscore (_) in markdown
" https://vi.stackexchange.com/q/18471/17441
autocmd Filetype markdown syn match markdownIgnore "\v\w_\w"
Custom additions to the dictionary will go to a simple text file (one word per line) in `~/.vim/spell/en.utf-8.add` (depending on your settings) where it is easy to edit or backup.
You can also add it directly when using it. Move the cursor to the word and (I forget the command...) can add it as a rare word, good word or bad word.
I am far more confident at spelling any Esperanto word that I have never faced before than I am with many common word in French which is my native language.
We can do better than blaming people for falling in pitfalls of a system full of odd traps.
Of course you are; Esperanto is a manufactured language designed to a certain standard; French, like our unfortunate English, is naturally evolved and has all the variants and inconsistencies that implies.
