Hello,

wouldn't it be a significant improvement and maybe a low hanging fruit
to add a macro allowing to add local pattern definitions?  I.e., like
`macrolet' by for pcase patterns?

It could help to make larger patterns better readable, by factoring out
long or repeatedly appearing patterns and giving them meaningful names.
Without cluttering the global namespace.

Maybe an implementation could be similar and as simple as that of
`rx-let'?


TIA,

Michael.
