Now *that's* neat.  I'v wanted to be able to do that for yonks.

Ten seconds of experimentation reveals:
        $ X == "Z"
        $ X Y
equates to:
        $ Z Y
whereas:
        $ X == "Z'"
        $ X Y
equates to:
        $ ZY

In short, the trailing quote prevents a space being appended to the
symbol translation.
