|IIRC from previous discussions, isn't this precisely the convention that

It is the origin of the bang name idea, but in fact they are
different.  As Hal pointed out, Scheme's bang is the mark for
self-modifying functions, on the other hand, Ruby's bang is the mark
for "more dangarous alternative; handle with care".
