A very slow (i guess) workaround could be:
"test".toUpper.only.map!(a => "This is a " ~ a).front.writeln;
vs the new one:
"test".toUpper.Identity!(a => "This is a " ~ a).writeln;
Shouldn't be slow, your just giving the optimiser some work to
do*, but you're always better off with the second one.

Trying on d.godbolt.com it seems a lot of extra-code is generated
for the first version.
Anyway I think I'm going to rename it "apply". :)
"test".toUpper.apply!(a => "This is a " ~ a).writeln;
It sounds better.
