use warnings 'wtf'

Is there any documentation for what all the various use
warnings 'foo'
are? perldoc perllexwarn at least lists them but doesn't
explain what
each one does, as far as my cursory glance suggested.

Specifically I wanted to turn off a "used only
once" warning triggered
by List::MoreUtils::pairwise which aliases $a and $b. Bit
surprised
the module doesn't document this as it seems like it'd end
up warning
more often than not for the common case.

(The answer is "no warnings 'once'")

  vi -R $(which_module warnings)

Perldiag is the correct manpage for this -- each description
begins
with something like "(W once)", meaning
"no warnings 'once'" will turn
it off.  (It's actually /\([WDS] (\w+)\)/.)
