I too was sad to see those function go as I frequently use them to
isolate data (formated as lua code) loading in my games.
I should be able to work around it though :)

Anyway I understand what you're saying and it does sound good.

That on the other side looks horribly un-lua-like to me (and unefficient
if the code in question is long enough), also this wont work for loadfile().
Concat some code before and after a string to change it looks so hackish :/
