Iβm aware of the trade-offs. :) Iβd rather use a digraph operator for mutating assignment, again with the Huffman coding argument. One design Iβm thinking of is using β@β as the mutable qualifier (e.g. β@intβ is a mutable int), and correspondingly use β@=β for mutating assignment. (The swirl in the β@β glyph is meant to allude to mutation, and itβs a character that visually stands out in code, as mutation should.)
