No. You do not get to create your own binary operators with any series
of random characters you choose. You are restricted to the ones the
language provides. I was a smidge diappointed when I first figured that
out myself.

No. You'll have to stick to Ada/Pascal/Modula/Oberon syntax for equality
and assignment. Sorry.

But on the bright side, you'll make less compilable typos this way.
