But sed, awk,
perl, python, ... lex and parse once into an AST or
bytecode, removing the recurring cost of comments, etc. that impact
groff. So I don't think it's an even comparison.
Of course it's a valid comparison. Which sed or awk or shell script is
distributed in a stripped/compressed form? Do they store their AST
somewhere, so as to avoid recompilation? They do not. Just as
with groff, every parse starts anew.
