Hello Thuna,

why do you want to behave `pcase' like that?

This would be a backward-incompatible change, breaking existing code.

And this change would break the symmetry between `backquote' the macro
and backquote patterns in `pcase'.  This is an important design idea.
And I don't see any advantage either.


Michael.
