Hello *,

What?
=====

We (see From: & CC: headers) propose, plain and simple, to turn the
currently defined type-synonym

  type FilePath = String

into an abstract/opaque data type instead.

Why/How/When?
=============

For details (including motivation and a suggested transition scheme)
please consult
