--[*label*[    ]*label*]

Where label is drawn from some set of characters (e.g., alphabetic, dashes,
underscores, etc.)

This saves humans the trouble of counting the asterisks when matching things
up. For example:


< insert Lua code here >


The trailing "--" is superfluous and exists just for a personal sense of
code symmetry in this case.


P.S. What's the timetable for Lua 5.1 these days?
