Re: On the subject of Lua's grammar... --[[ ]]

[Mark Hamburg <mhamburg@...>]

--[*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:

--[*test-harness*[

< insert Lua code here >

]*test-harness*]--

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?
