Inline has always been centered around defining wrapper functions. Now
you can definitely do this:
---8<---
use Inline::Files;
use Inline C => BELOW => PREFIX => 'X_';
print erf(0), "\n";
print erf(1), "\n";
__C__
double X_erf(double x) { return erf(x); }
---8<---
So the Perl interface is preserved.

I'll discuss the patch with Neil. He was the last one to touch the
grammar.

Oh definitely. And patches are always very much appreciated. (Doesn't
mean they'll always get in) A great way to say *exactly* what you mean!
Cheers, Brian
