21: warn for keys/items/values/range r=ltratt a=nanjekyejoannah

I think I was over-thinking the solution with flags at synbol table generation. I found a simple check at the AST that checks correctness of values assigned to wanr for things like "True" and other keywords and used this check to warn for these calls.

This warns for `keys/values/items/range`:

Accurate when the statement is in an assignment:

`x = range(20)`
` y = d.keys()`
