Type capture in subroutine strangely works in some contexts but not others.

(Int)

It looks like it may has something to do with the handling of the
comma operator. A superficial investigation shows that, "recently",
only the release 2015.09 worked correctly, others before and after
don't. I couldn't find the commit before 2015.09 that made things
starting work. After 2015.09, bisectable6 pointed to this commit
which introduced the error:
https://github.com/rakudo/rakudo/commit/03f84eea11dc4b0c49d78844d2a8fac0981152a2
(Not sure if this is already reported; this may be a duplicate)
