That was my first idea, but I worried that ${NAMES} could break the
template. In <style>s for example, that syntax might cause editing programs
to complain about malformed stylesheets.  The enforcement of the '${}'
delimiters (or any other reasonable choice I could think of) practically
guarantees that placeholders will make lousy template text.
