I'm not so sure about the utility of this in my case. I usually end up using python for scripts, with perhaps a one line batch file that runs it with some default arguments for convenience.
Yup, that's all we end up doing, but it would be nice to have something that combines both programming bliss with end product being just one Bash script that runs on every Linux distro.
I have to confess, that I'm also one of those guys. I usually anyway installing Python anyway. So using it all scripting is trivial. Even if Python is "heavy and slow", people seem to forget that Powershell is lot heavier and slower.
