I shudder every time someone says "macro" on p6i. perl5 has several thousand macros defined. (grep for ^#define) (over 8000 if you include all the embedding macros. it's down to ~4000 if you cut out embedding, config.. and closer to ~1500/2000 if you rip out more things.) This makes it wonderfully challenging to debug. Macros are a useful feature of the C language, but we should be very careful in how we use them. (I'm not saying don't use them at all.) I'm sure there's a happy medium somewhere between no macros and perl5. We should look for it. -R
