text/template: Funcs accepts names with '-' but won't allow calling them

[anacrolix]

I've given a valid function but with a name containing '-'. Attempting to call it from a template:

panic: template: index.html:64: unexpected bad character U+002D '-' in command

[minux]

I agree that we should reject uncallable Funcs.

I am confused now. How did you get a panic? The parser correctly returns an error for a template that attempts to invoke such a function.

I'm starting to wonder if the original CL (tweaked) is all that's required.
