- Is there a reason help.c is written in C rather than Lua?
- What's the name of the syntax the help pages are written in? It
appears markdown inspired.
- One alternative to help"math.sqrt" is to support help(math.sqrt).
 does the latter, and Python supports both [1-3] as well as things
like help("keywords"). help(getname(math.sqrt)) might be another
approach. To distinguish package functions and object methods, e.g.
io.write and file:write, I see LuaHelp currently uses help"io.write"
and help"file.write", which could become ambiguous, though I'm not
sure what the ideal way to uniquely name object methods is
- Python invokes the pager (less) rather than just a print. In Lua,
someone can always redefine print to obtain a similar effect: function
print(s) local f = io.popen("less", "w"); f:write(s); f:close() end .
