Re: [perl #127188] [IMPROVEMENT SUGGESTION] :lang on eval to attempt to use an Inline::FOO module

[Tobias Leich]

I still think that language modules like Inline::* or v5 need to 
register itself. Which means, you'd use such a module before doing the 
EVAL so the EVAL knows what module handles the requested language.

Seeing that value of 'Perl5' for the :lang argument to EVAL attempts to load Inline::Perl5, 
I'm curious whether we could possibly make it attempt to work for ANY language by loading 
the appropriate Inline:: module. In other words, :lang<Lua> would attempt to load 
Inline::Lua and :lang<Ruby> would attempt to load Inline::Ruby, both of which exist 
in our ecosystem.
