Test case #​1​:
  ./perl6 -e'class Foo​::Bar {}; say Foo​::Bar.new.WHAT'
Got​:
  Bar
Expected​:
  Foo​::Bar

Test case #​2 (which is just a special case of test case #​1)​:
  ./perl6 -e'class Foo​::Bar {}; say Foo​::Bar.new'
Got​:
  Bar<0x4099e80>
Expected​:
  Foo​::Bar<0x4099e80>

A PIR implementation for the expected stringification is​:

.sub 'wibble'
  .param pmc x
  $P0 = x.'HOW'()
  $P1 = getattribute $P0, 'longname'
  $S0 = $P1
  .return ($S0)
.end

But I'm not sure what to call it or where to put it... Maybe
P6protoobject's vtable(get_string) should return 'longname' instead of
'shortname'?

Bar

Rakudo has the correct behavior here -- .WHAT stringifies to
the short name. From Synopsis 12, "Introspection"​:

  Metamethods for objects are named with interrogative pronouns in uppercase​:

  WHAT the prototype object of the type, stringifies to short name
  WHICH the object's identity value
  WHO the package supporting the object, stringifies to long name
  ...

Test case #​2 (which is just a special case of test case #​1)​:
./perl6 -e'class Foo​::Bar {}; say Foo​::Bar.new'
Got​:
Bar<0x4099e80>
Expected​:
Foo​::Bar<0x4099e80>

There might be an argument that we should use .WHO for default
stringification -- but (1) we don't have an implementation of .WHO
yet, and (2) much of this is speculative anyway since there aren't
any specifications or tests for this behavior. Thus I'm inclined
to leave things as they are for now.

Thanks!
