Enhance selector and case statements to match with regexp

The case and selector statements define ephemeral vars, like 'if'.

Usage:

case statement:
$var = "foobar"
case $var {
    "foo": {
         notify { "got a foo": }
    }
    /(.*)bar$/: {
         notify{ "hey we got a $1": }
    }
}

and for selector:
$val = $test ? {
  /^match.*$/ => "matched",
  default => "default"
}
