Issue #11390 has been updated by D.E. Akers.


Permitting such syntax would needlessly complicate the parser for virtually no gain, and potentially break existing code that uses a numerical literal as the alternative of a non-padded ternary expression (`foo?1:2`). Just use `:'1twothree'`.

Feature #11390: Allow symbols starting with numbers

----------------------------------------
Currently it is not possible to create a symbol that looks like `:1twothree`.

Converting to a string and then symbolizing causes hash lookup problems and proves counter-intuitive. What's also surprising is that ruby allows symbols to start with special characters but not numbers.
