Another alternative is to use function calls for sequence operations and
leave operators just for comparisions. To have the same syntax element do
multiple jobs, depending on context, can be a source of problems.
I agree with the C and Pascal comments you make, but the difference there
is that they are only dealing with assignment and comparisions, not
sequence operations as well. In Euphoria, '=' is used for three distinct
actions, depending on its context. I would propose that it, and the other
comparison operators, should be deprecated for sequence operations and
those (rarely used) activities be replaced with built-in functions.
