Re: Possible Lua enhancements 2: Piping

[Mark Hamburg <mark@...>]

Having said it would be easier to write in C, now I'm worrying about  
how to write pipe in pure Lua...

function pipe( fn, ... )

	if select( '#', ... ) == 0 then
		return fn
	else
		local rest = pipe( ... )
		return function( ... )
			return rest( fn( ... ) )
		end
	end

end


As long as one reuses the pipe, the cost of the chain construction  
probably isn't too bad.
