Another possibility: I've used "f ** g" for function composition of "f" and "g" in some of my code. It seems quite intuitive to me, a sort of multiplication operation in the "monoid" of functions. Maybe people accustomed to using "**" for the power function will find it weird, though.

After reading all your posts and all previous posts I could find, I've started using (<--) and (-->), but I also wish there was an agreed upon notation for this.
