The problem with CWD is that as far as I know there is no notion of
"working directory" in ANSI common lisp.

This means that implementing CWD would require writing
implementation-specific code for every CL implementation we support.

Also, how should we interpret :CWD when we are reading the DSL from
environment variables, configuration files, etc.?

There is a :HERE directive.  Is that not sufficient to you?
