What is the idiomatic way to extract first/last item after split?
More interestingly, why #2 doesn't work, while #3 does?
For example:
$path = `cd`;
# 1. working, but I've been told not very efficient:
$base = (split /\\/, $path)[-1];
# 2. this isn't working for me. Why???
$base = pop split /\\/, $path;
# 3. This is similar to above, but does work.
@tmp = split /\\/, $path;
$base = pop @tmp;
# 4. Work, but I believe slower:
($base) = $path =~ /.*\\([^\\])/;
