in reply to Macro system on B-Level?

If all you're doing is saving function call overhead, it's not worth the trouble. If performance is that critical, drop down to XS or Inline::C or such like as.

Between the mind which plans and the hands which build, there must be a mediator... and this mediator must be the heart.

    No, no, no, your getting me wrong!

    It's *not* about function call overhead, it's about realising *macros* ¹, therefore helping to extend the syntax much better and reliable than codefilters ever can.

    perl 6 also intends to insert macro-support.

    But maybe you can show me a functional approach to solve this problem. : )

    UPDATE: (¹) to make it clearer, a macro is executed and operates on the parameters given before returning the new code to be inserted.

    I'd rather prefer using some kind of eval like  eval macro() than doing XS.

    Coding in C just for linearising the code *that's* not worth the trouble. : )
