1962,:instanceof('Foo') is untested,cotto,,"imcc has a little-known sub modifier that causes a Sub to be created as an alternate PMC type.  The one place it's documented, PDD19, contains the following description:

The C<:instanceof> pragma is an experimental pragma that creates a sub as a PMC type other than 'Sub'.  However, as currently implemented it doesn't work well with C<:outer> or existing PMC types such as C<Closure>, C<Coroutine>, etc.

This needs to be added to DEPRECATED.pod as an officially experimental feature and, more importantly, needs to be tested.",todo,new,normal,,imcc,2.11.0,medium,,,,,,
