[swift-evolution] [Proposal] Refining Identifier and Operator Symbology

The "Symbol, Other" category contains "Sign of the Horns" 🤘 which was one of the problems with the identifier/operator that kicked off these discussions.
So it would break some existing cases, e.g.:
1> let \U+1F913 = "nerd face"
🤓: String = "nerd face"
On the other hand, there are some symbols in [:So:] that may be useful e.g. the APL Functional Symbol * series
It might be easier to have just [:Sm:] to start with, and review the [:So:] subsequently (or have those addressed in UAX31).
