You can create Functions named with keywords. Breaks on compilation.

[t-eckert]

Steps to reproduce

cargo func new-app some_app_name  
cd some_app_name
cargo func new http -n do
cargo func run

Expected behavior

Any time that a user tries to make a function named after a Rust keyword, they should get a warning and suggestion to try something different and replace the keyword with the escaped version (e.g. do -> r#do).

Actual behavior

Nice find.

I think we should have a list of problematic names that require use to use a raw identifier (r#do from the error message).

We could pass the template whether or not the name is reserved and if it is, use the r# prefix. This would enable things to work without explicitly disallowing such function names.
