All section names that also happen to be names of builtin methods of str to result in broken output if their value is a plain string and not a dictionary.
The example below uses upper as a section name, but the same thing applies to the any function name that can be called as a method of a str object like zfill, encode, endswith, replace, etc.
Minimal example to reproduce (python 3.7, chevron==0.14.0), derived from here by just changing names.
import chevron
chevron.render("{{#upper}}{{{.}}} == {{{upper}}} {{/upper}}", {"upper": "foo"})
Expected output:
foo == foo
Actual output:
foo == <built-in method upper of str object at 0x104383e30>
Version 0.13.1 does not show that behaviour.
It seems that the change in #87 introduced the bug as a side effect of using getattr() on a variable that isn't guaranteed to not be a string.
