[msh210]: I think I just found a lie in perldoc.
[msh210]: warn: "If the last element of LIST does not end in a newline, it appends the same file/line number text as die does."
[msh210]: perl -e'warn "test$/", "" '
[msh210]: doesn't append anything.
[msh210]: It should say "If the last nonempty element of LIST" or "If the string thus to be printed does not end in a newline""
[msh210]: Am I wrong?
[shmem]: no. You're right.
[msh210]: About time... last time I was right was... I don't even remember when.
[shmem]: perl -e 'warn "test$/", ^@^ '
[Eily]: well, at least it's right about warn doing the same thing as die :)
