What about including mutation information in the stack comment? So for
instance, sequences:copy would be:
: copy ( src i dest! -- )
...
And if something has a side-effect on something not on the stack then it can
have some other notation:
: set ( value variable -- !)
...
By setting these comments on primitives we could infer them about other
words like we do with stack effects.
Of course, it's still confusing to use ! for this, but any old
non-alphanumeric character will do. What about #?
