If you're being serious, then you're sticking very intentionally to the very small subset of Ruby that compiles to Crystal and missing out, unnecessarily, on the very amazing features that both languages offer to no great advantage.
I tried this very thing, and very quickly started looking for other options, landing on mruby. Compiled mruby is almost as fast as just writing bare C. I just compile an mruby interpreter and use that to run .rb files when I want speed. It's fast enough for me.
Much, much better than trying to shoehorn Crystal into this role.
You're right, Crystal might not be the best choice but it does the job so far.
Shipping compiled binaries is so sweet, having to force every user to install the Ruby runtime isn't fun.
Thanks for the tip, looks like mruby is even a better way to provide portable ruby scripts. I'll check it out.

That's interesting!
Just tried mruby and it seems to work very well, the packages seems enough for me aswell.

You're using the wrong option, the one you want is at the bottom, where you use the -B option to dump the bytecode into a C array, which you then wrap with a bit of boilerplate so as to compile into a standard executable. Once you understand it it should be easy enough to script.
