minimal PostScript interpreter

Problem

And we really mean minimal. The idea is to restrict PostScript to as few operators as possible while still remaining interesting (unlike that disaster of a minimal Scheme interpreter problem not too long ago).

That is, the operators must allow for deterministic but variable output. Having no output is trivial, and outputting only identical values is boring. And nondeterministic output is just too crazy.

Since there are no existing operators that produce output while increasing the size of the operand stack, this cannot be accomplished with fewer than two operators. As it turns out, we can make do with just two operators: a creation operator (count) that adds values to the stack, and an annihilation operator (=) that consumes values and outputs them.

count -- this operator counts the number of objects currently on the operand stack and pushes this number onto the top of the stack (effectively increasing the stack size by one)

= -- this operator pops the top item off the stack and prints it to stdout, followed by a newline (effectively decreasing the stack size by one)

A legal PostScript program consists of a sequence of tokens separated by whitespace. For convenience, the whitespace in this problem will be a single space between adjacent tokens.

This is the challenge. What will your interpreter's character count =?
