I often wonder about extending a known languange; therefore inheriting
all its scoping, looping, conditionals, arrays, dictionaries, text
processing, file-io, maths, strings, regexps etc, but adding
PostScript's path-construction, graphics-state and painting stuff.

So, eg in Lua (my current favourite language :-)):
  gsave(); translate(80,80); concat(0.7,0.8,0,4,0,0); moveto(0,0)
  selectfont('Helvetica-Bold',60); show('FASTEN SEAT BELTS!')
  grestore();

instead of
  gsave  80 80 translate  [0.7 0.8 0 4 0 0] concat  0 0 moveto
  /Helvetica-Bold 60 selectfont  (FASTEN SEAT BELTS!) show
  grestore

Of course there is an associated anathema-problem :-)

And it depends on whether ghostscript exposes these things
in a library in some kind of useable way...

mmm...
