Yes, I said "documentation" for a reason. Since when people have to go looking
in PEPs for rationale of a module? string.Template introduces a very clear
TOOWTDI conflict, I think the documentation should mention and try to explain
it. For instance, the documentation for Decimal is pretty clear as to when
Decimal is to be used and how it is different from float.
