Claims about "=" and "==" without substantial statistical and economical
evidence are just not going to cut it, I think. On the contrary, they
might reflect on the speaker and his favorite language. Also, what is the
general impact of "=" when comparing effects of other features that
supposedly have caused or prevented issues, like run-time bounds checking?
Has discussing these issues ever helped choosing languages, influencing
the choice in the direction that a programming engineer would?
If not, what is a good way of discussing language design?
I think there is a story by Hofstadter about the magic that symbols
can work on young people.
I submit the common length of "==" and "!=", and some languages' choice
of "=/=", perhaps all but APL lacking "≠". The latter also officially
uses "←" for assignment, not sequences of punctuation available through
iterated pressing of single buttons on the ASCII keyboard. ;-)
Also the convenience of being able to compare two objects for
being the same object, using "===" in some languages---out of the box!
procedure same_object (A : T; B in out T) is
begin
what_do_i_put_here; -- ?
end same_object;
