`letm` as a syntactic sugar for `let mut`

[abhijeetbhagat]

i propose introducing a new keyword letm as a syntactic sugar for let mut. this saves 4 characters.

[petar-dambovaliev]

I don't think this is a good idea. There are many other places where you could save characters in the language. Rust already keeps a good balance of not writing too many characters but also not too few, so it's not a burden but also readable.

If typing it is an issue for you, you could propose autocompleting letm to let mut in code editors instead.

Also, there are many occurrences of mut for bindings (e.g. parameters, match, let Foo(mut field)) that you cannot save the character for, and possibly (citation needed) &mut is way more prevalent than let mut if you want to save characters somewhere.
