simple-expr

Minimalistic toolkit for simple mathematical expression.

This is a minimalistic toolkit for simple mathematical expression developed for debug purposes similar to 'simple-reflect' package but based on slightly different principles. In particular, we use ordinary syntactic trees instead of turning them into strings. There is a primitive manipulation capability like

>>> simplify $ (x + 0) * 1 - x * (3 - 2)
0

Besides an expression visualization feature is also provided.
