This is super exciting but I wish they added a function to render the template to a string rather then having everyone write their own version of basic rendering.

One place we landed with PEP 750 is that Template instances have no natural string rendering.

That is, you must process a Template in some way to get a useful string out the other side. This is why Template.__str__() is spec'd to be the same as Template.__repr__().

If you want to render a Template like an f-string for some reason, the pep750 examples repo contains an implementation of an `f(template: Template) -> str` method: https://github.com/davepeck/pep750-examples/blob/main/pep/fs...

This could be revisited, for instance to add `Template.format()` in the future.

I totally agree with `Template.__str__()` == `Template.__repr__()`, but I would strongly be for adding a `Template.format()`. I expect that over time I'll be passed template strings where I expected normal strings and adding that example `f(template: Template)` everywhere to my code bases is just a lot of repeated code for no real value.

That said, I think this is a great bit of work and I look forward to getting to use it! Thank you!

I'd agree that it should be somewhere within the library, even if it's just a separate top-level function in the described `string.templatelib`. If it isn't, I'm sure someone will make a PyPI package for it right away.

PEP 501 allowed `.format()` to do this, but discussions on PEP 750 felt that format shouldn't be needed, because when you need a basic format, you should probably just use f-strings. But maybe `__format__` can be added in in a future version of python if this is really wanted.
