It may be easier to discuss here.
* First it needs to be decided, if such a check in itself (ignoring any
obstacles in it's implementation) has a chance to be accepted at all.
IMO a better check would create a (true, unique) copy of every string on
entry of a procedure, and compare the parameters against these copies on
exit. This will not modify the behaviour of the code, because the
refcounts are not altered, and it will catch *all* modifications, that
may have altered the strings.
Dunno whether and how such a feature should be implemented in the
compiler - my suggestion can also be implemented in code, perhaps
assisted by macros for easy on/off switching.
