My question would be: why are sh and C the only choices?  If the answer 
is "because that's all we have in base", is that a valid concern?

As far as sh, it lacks many high- or even mid-level constructs and has 
real problems with quoting, parsing, and output (2>&1 >&3, for example). 
These make it harder to do things (aka, more code to accomplish a task, 
more code to be maintained, more difficult to modify) than the higher 
level Perubython languages.

In any case, thanks for working on this.  A functioning program in any 
language is better than a non-existent "better" one.
