Re: How not to remove trailing empty strings from an array

in reply to How not to remove trailing empty strings from an array

Close, but subtly different (imho), it

is an infinite loop if @msgstr becomes the empty list because then -1 returns undef, which causes length to return undef, which is false and gets negated.
You could fix this by using pop @msgstr while !length($msgstr[-1]//0); instead (perl v5.10 and up)

My actual fix was `pop @msgstr while @msgstr && !length($msgstr[-1]);` [download]	[reply] [d/l]
