Just `mut` alongside `let mut`

Hi,

I suggest/recommend support for just the mut keyword for mutable variables alongside existing let mut

If we cannot accommodate mut, can we think of a new 3-character keyword that rhymes with let - from soundex or other criteria?

Some suggestions ...

tel - the reverse of let

cut

set - highly recommended for clarity - (clean, clear, crisp) !
