For me, touting a language as being "Python, but with X" is a big turnoff.
I worked for about 2 years in Python and hated most things about it - from the whitespace sensitive indentation that led people to write really long lines and the limited expressive capabilities forcing people to do meta voodoo in their libraries leading to incomprehensible DSLs, to the legacy that sticks like "old-style vs new-style classes", to the performance problems and the sad state of libraries in the ecosystem, let alone the complete cluster-fuck that is dependency and deployment management on top of Python.
So you know, I want to hear about languages that are not like Python.
Oh, then you'll love Go. It's nothing like python. At least, not like the python you've described above.
Go is actually quite different from python in a lot of ways. Most of the stuff you hate about python does not apply to Go in any way. You can't really make a DSL in Go - there's no operator overloading, no meta classes... no classes at all. The performance of Go is an order of magnitude faster than python and only a few times slower than C. Dependency management and deployment are trivial - Go compiles to a standalone binary with no dependencies (except sometimes libc depending on what you're using).
So... Go is nothing like Python. When people say it is, what they mean is, Go tries to make its syntax really obvious, and make life pleasant for experienced developers writing software in the language.
