Very nearly, except that ~~ merely promises to return something
that can be used as a boolean, not something that is of Bool type.
And, in fact, for a normal regex you'd get a Match object, which as
a form of Capture would then try to compare itself back to $pattern,
which is not what you want. So you'd have to force it:
given $pattern {
when true $a ~~ $_ { ... }
when true $b ~~ $_ { ... }
when true $c ~~ $_ { ... }
}
