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"?
Many thanks,

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

Hi W,
Subset does no seems to be what I am after, but "where"
does. Thank you!

Hi W,
I might be changing my mind. It would not be the
first time you have done that to me.
