Re^2: qw() problem

HI,

careful with those comma's:

perl -e '@a = qw(a, b, c);map { print "$_\n"; } @a'
[download]

gives:

a,
b,
c
[download]

While:

perl -e '@a = qw(a b c);map { print "$_\n"; } @a'
[download]

gives:

a
b
c
[download]

With qw you can skip the comma...

UPDATE: sorry for the spelling mistake. It's commas! I've been reading slashdot too much lately.

Not can skip but (in most cases) should skip. OTOH: You should have replied to the OP. I know of that fact, that's why I said that it's equivalent to `('name1,', 'name2,', 'name3')` [download] and not `('name1', 'name2', 'name3')` [download] Update: Just a side note ;-) Careful with those apostrophes! Generally there is no such thing as a plural apostrophe in ~~any language I know of~~ english and german. So it should be "commas" not "comma's" ;-) Update 2: Thanks to Perl Mouse I've learnd that the dutch language has a plural apostrophe in some cases. That's the reason for the correction above... `$\=~s;s.;q^\|D9JYJ^^qq^\//\\\///^;ex;print`	[reply] [d/l] [select]
