Now fixed in ee1fd13:

$ ./perl6
> say &infix:<+>.WHAT
Multi()

Assigning to moritz++ for spectest coverage, if needed.

I've written a test for this in S12-methods/what.t in r27345.

# RT #66928
{
lives_ok { &infix:<+>.WHAT }, 'Can .WHAT built-in infix op';
isa_ok &infix:<+>.WHAT, Multi, '.WHAT of built-in infix op is Multi';
}

Second one probably wants to be:

ok &infix:<+>.WHAT ~~ Multi, '.WHAT of built-in infix op is Multi';

As implementations are not obligated to have a Multi isa-type but may
have a Multi role mixed in or some such...
