in thread quick question on modules

A great counterexample is POSIX:

Q:\>perl -MPOSIX -wle "print for grep {$_ =~ /$$/} `tasklist`" perl.exe 5508 Console 0 3.936 +K Q:\>perl -MPOSIX=strftime -wle "print for grep {$_ =~ /$$/} `tasklist` +" perl.exe 4904 Console 0 3.672 +K

POSIX.pm exports all its functions and constants by default, which costs 300K memory, while importing just the few needed functions reduces the amount of memory spent.

tl; dr - just like you said, no general answer here.
