Doesn't seem very clear...it seems to be a shortcut for "evaluate", and
you aren't evaluating a variable, you are setting it to a specific value.

I think some of us still keep in mind the happy times of DBW-render 1

Used in isosurfaces. (evaluates the max_gradient)

It might allow simplifying the parser to allow faster parsing, and
provides a visually obvious cue to the end of the statement(which can be
several lines and several {} blocks down, like in the case of layered
textures).

It may also cause problems if you use it in odd places, like:
sphere { <1,2,3>, # a = 1 2 pigment { rgb 1 } }
You may think that it's an unrealistic example, but it isn't.

Personaly I don't need or like them for that, I forget to put them in very
often and pov runs ok, except for the warnings.

You mean not using a semicolon will cause problems, right? Because I
don't think a "# VarName" feature would cause trouble.

When semi-colons were first introduced I bitched up a storm about
them. They are particularly bad in the windows version if you have
"message stream to consol" turned on because all of the warning
messages chew up cpu cycles like there's no tomorrow. I finaly
broke down and forced myself to use them and it has become almost
second nature to use them now. I could do without them but if
the parser runs better with them I can live with that.

That was what I meant. If you don't use a semicolon, the parser may get
confused.
