I have never used -> but I noticed at

that some people do. In fact, the above-named code has a sort of elegance about it (except for
the use of "=" for assignment...). To my eye, -> calls to mind a type of
assignment that is meant to stand out. For example, perhaps it would make sense to use ->
to assign to things that are not expected to vary through the rest of the code block.
Q1: is there a convention, informal or otherwise, on when to use the ->
operator?
My recommendation would be "never". It's rarely used and unnecessary,
so you'll just confuse people. It also looks identical to the ->
operator in C for pointing to a member of a structure, another cause for
confusion for some people.

Q2: if there is no convention, but if people think a convention might help,
what would that convention be?
