Trying out Method::Signatures::Simple  I previously wrote about
trying out MooseX::Method::Signatures. That module is neat, but
incurs a significant runtime penalty per subroutine call.  Now
I've tested out Method::Signatures::Simple. It's powered by
Devel::Declare and doesn't seem to incur a any runtime penalty.
However, since it needs to do some work when the subroutines are
compiled, there's a 3-4% compilation hit for my tests:  But on
runtime there's no hit at all:  Here's what I needed to do to
convert Hailo to it. Unfortunately using it breaks interaction
with Devel::NYTProf. When I generate profiling output with
nytprofhtml what were previously links to my subroutines aren't
links at all.  That's a big price to pay for just turning this:
Into this:  So unless I can figure out a workaround for that I
won't be merging that branch.  Leave a comment  About Ævar
