Possibly tangential:

(%i7) load("unwind_protect")$

(%i8) simp_using(e, [fcts]) := block([cntx],
  unwind_protect((
      cntx : supcontext(cntx, global),
      apply('assume,fcts),
      expand(e,0,0)),
    killcontext(cntx)))$

(%i9) simp_using(abs(x), x > 0);
(%o9) x

(%i10) simp_using(abs(x), x < 0);
(%o10) -x

(%i11) contexts;
(%o11) [initial,global]

(%i12) map('facts, contexts);
(%o12) [[],[equal(%e,2.718281828459045), ...]
