I have a list of files I want to case-insensitive sort by extension, files

various syntax for this one - there MUST be a better way than my feeble attempt:
I'm never one to abuse working code, but if your definition of "better" has something to do with sorter, a simple Schwartzian Transformation seems to work:
@input = map { $_->[0] }
sort { lc($a->[1]) cmp lc($b->[1]) }
map { m/\.([^.]+)$/ ? [$_, $1] : [$_, ''] } @input;Hope that helps.
