Hi All,
In a sub declaration, is there a way to constrain

Hi Joseph,
I like it.
Now to figure where to put it so it is apparent
This can be done with an explicit, named subset if you like:
subset StrOrInt where Str | Int;
sub do_stuff ( StrOrInt $item ) {

Hi, Todd,
If I understand your question right, then you mean something like that:
sub do-soemthing($value where { .WHAT ~~ Str || .WHAT ~~ Int }) {}

Hi All,
In a sub declaration, is there a way to constrain
a variable to only an "int32" or a "Str" (I want both)?
Or do I have to put up with the other types of "Any"?
