I like this idea very much. I believe '&' should belong to instance
variable, as it will be mutated, just like for inout parameter, so
c&.frobnicate(i)
let k = c&.frobnicate(&i)
very clear and explicit. Don't like the 'mutation' or even 'mut' as we'll
have heavy code, as it is a word just like functions/methods/variable names
and IMO harder to parse visually. '&' is a 'marker', that clearly parsed.

As an alternative to the mutate keyword I rather like using '&' because it
already means 'inout'. Using '&.' as mutating method call would therefore
be quite understandable.
c&.frobnicate(i)
let k = c&.frobnicate(&i)
Or marking the method like suggested elsewhere:
c.frobnicate&(i)
let k = c.frobnicate&(&i)
