Has anyone tried to do Lua code in .rtf?
That is, a reader (chunk loader, whatever) that reads in not .lua (raw ansi text) but a document that can have bold, italics, underlinings, even pictures.
I had this idea about 10 years back, using Borland C++. Why couldn't source have commenting pictures etc. attached right there. But it doesn't. Not even in 2003. :)

This will result in totally unreadable/misinterpreted code, IMHO. The
assumption that '+' can somehow intuitively be realted to '|' is ungrounded
to say the least.
On the "all programming languages look like C" planet, perhaps. For the
rest of us, the use of | for a set union operator is totally baffling.
My first choice would be the standard mathematical symbols. But that
requires Unicode - maybe the industry will have got its act together in ten
years or so. I want to be able to type these things easily.
My second choice: + for union, - for difference (A - B is the members of A
that are not members of B), and * for intersection. The empty set is nil.
Then you can say
FOO_ALL = FOO_BLUEPANTS + FOO_3PLANES + FOO_EDIBLE + FOO_WOBBLY + FOO_ALIEN
if flags * (FOO_ALL - FOO_EDIBLE) then
I believe this can be implemented in pure Lua, or with C helper functions
for speed. Certainly no changes to the core language are required.
