        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,
        -T

    Hi, Todd,

    If I understand your question right, then you mean something like that:

    sub do-soemthing($value where { .WHAT ~~ Str || .WHAT ~~ Int }) {}

For the sake of readability you might want use a subset:

Hi W,

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