This is exactly what "when <expr> block" does -- it smartmatches
<expr> against $_. The problem is that there are at least two
interpretations of a true result of <expr>:
when True { ... } # execute when $_ is exactly "True"
when foo() { ... } # execute when foo() returns true
It's been decided that the latter is far more useful in general;
there are plenty of ways to express the former that are much
less ambiguous.
