No, please don't!  I was suggesting ":=", not "=", and I wasn't
serious.  A lone equal sign is used in too many languages (e.g.
standard mathematical notation, standard pseudocode, Pascal and its
descendants, etc.) to indicate a statement or test of equality.  The
mis-use of it in Fortran, C and BASIC aren't examples we want to
follow.

I think we're stuck with "<-", despite the deficiencies I pointed out
in my earlier message, and we should learn to live with it.  I'm
ambivalent about " _ ".
