Request - support for recursive variable definition

[sunyatasattva]

Why doesn't LESS allow for recursive variable definition? As seen in:

var a = 1;
a = a + 1;

or in pseudo-LESS

@a: 1;
@a: @a + 1;

Does it have to do with the lazy loading system? And why would it be a bad idea to support this kind of syntax?

Less is declarative, it doesn't run your css from start to finish. So the
variable declaration used is always the last in all files, not the last
going up from the current place.

You could make variables use different rules if they self reference, but I
think it gets very complicated and inconsistent.

What are you trying to do that you can't?
