Implicit multiplication parsing issues

[Tom-the-Bomb]

I'm making a basic algebraic/mathematical equation parser, and I'm having a problem where unary operations make things a bit odd.

with unary operations implemented the way I have: 1 + 2 + 3 : 2 + 3 gets evaluated before 1 + 2 even though addition associativity is left.

Removing the unary operation rules and also there are also a couple of other changes fixes that but that messes up the precedence for implicit multiplication where: 1 + 2x : 1 + 2 becomes 3 before 2x becomes 2*x

I have no clue what's wrong

(Combining the code in the rply documentation example produces the same problem)

As a reference, this commit adds support for expressions like 3a+4b:

Thank you for that, but I've managed to work out a solution myself that passes my current test cases. :)
