It's not about having to remember them, it's that you shouldn't waste these short single symbols on operations that are only rarely used.

This stuff (especially the ternary) are a step backwards. There is just no reason to waste | on a bitwise or that gets used at 1% of the frequency of the standard or. In the future you might have a better use for it (pipeline syntax, sum or union types come to mind in other languages).

I dislike basically everything about these syntax extensions.
