support env!()

[GGORG0]

Hi, I'd like to obfuscate a string from the env!() macro. It returns a &'static str, so this shouldn't be a problem, right?

It is.

#[muddy]
static BACKEND_ENDPOINT: &str = env!("BACKEND_ENDPOINT");

error: Expression must be of type &'static str

The error is unfortunately not very helpful here, since the macro really only expects string literals. Thanks for bringing this up.

However, I'm pretty sure that what you're attempting should be possible - I'll check it out!
