4c: Tank Printer
++re
Pretty-printing engine
Pretty-printing engine that accepts a ++tank sample and contains arms that perform computation on it.
Accepts
tac is a ++tank.
Produces

++ram:re
Flatten to tape
Flatten ++tank out into a ++tape.
Accepts
tac is a ++tank, taken from sample of ++re core.
Produces
