I agree with you, but you got me thinking. How about this:
#usage: @result = st_complex sub { complex comparison }, sub { transfo
+rm }, LIST
sub st_complex (&&@) {
my $compare = shift;
my $transform = shift;
map { $_->[-1] }
sort $compare
map { [ $transform->(), $_ ] } @_;
}
#usage: @result = st_simple sub { transform }, LIST
#note: comparison is string wise.
sub st_simple (&@) {
my $transform = shift;
&st_complex(sub { $a->[0] cmp $b->[0] }, $transform, @_);
}
The only shortcomings I can find are that
sub NAME (&&@) won't allow you to call
NAME { CODE } { CODE } LIST, only the first code block can be a bare block, and I can't thing of an effective way to combine the two into a single function like
sort.
