this is just a quick note related to the thread "Adding new Inline::C subroutines at run-time".
Using Nicholas', Matthew's, and Patrick's suggestions, I have spent a few hours of this sunny day writing a module that uses Inline::C to generate C code from mathematical formulae (Math::Symbolic trees) and make them availlable through Perl closures. The result can be found at http://steffen-mueller.net/modules/Math-Symbolic-Custom-CCompiler/
It'll be on CPAN as soon as it has propagated to the mirrors.
