admittedly square brackets do not look more pleasant. :-/

using multichar sequences that look like comments to older Lua
versions and hence would be ignored by those is no bad idea,
right ?

but then this might boil down to something more in line with
Lua's multiline comments:

--[==...==[@ attr arg1 arg2 arg3 ... @]==...==]

which admittedly does not look too pleasant aswell ... :-/
