-> is usually only used when you suddenly remember you wanted to keep result of a computation, especially in the days before command-line editors were universal.

fn(a,b) ... oh I'd better keep that ... -> z

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?

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