I am of two minds on this. Sometimes I want x² to parse as x*x (an
operator) but other times I want to store the value of x*x in an identifier
spelled… x². This could be simply to avoid repeatedly performing the same
calculation, or it could be the natural result as in,

let r² = someStatisticsThing(xVals, yVals)

Not sure where I’m going with this, just wanted to mention it.
