I actually think it is a strength or really being able to use Cython to compile Python into C/C++ is the strength. There aren't too many scripting languages where I can do very little work/setup to get C-like performance, and I can still use Python and its huge ecosystem. Nim looks interesting because it provides a simple, concise scripting language like Python but makes compiling to C/C++ dead simple. Nim is just missing that ecosystem.
