Yes, I sometimes need this for el-searches.

I wondered what happens when a pcase form binds a symbol S that is not
defined at compile time (normal case) but then a user loads a package
that declares S as (globally) special. Then that pcase binding gets
dynamical scope at runtime (as it would happen with any `let' binding),
right? Sorry if this is silly or trivial, I was just wondering...
Michael.
