|     Unfortunately, splice patterns in brackets still do not work
|     because we don't run splices in brackets. Without running a pattern
|     splice, we can't know what variables it binds, so we're stuck.

Not just "don't" but "can't"!!  This isn't a compiler deficiency: the code is not there to run!
