That's very cool. Yes, mea culpa, pl/init.lua is a devious piece of code.
For those unfamilar with the strategy, it does lazy loading of
modules. This is to make life easier for lazy programmers:
require 'pl'
local d = arg[1] or error 'provide a directory'
if path.isfile (d) then
for f in dir.dirtree(d) do
print(f)
end
end
require 'pl' does not actually bring in the whole 10K of the complete
library, but defines the subtables like 'path', 'dir', etc with a
custom __index. If you try to access a function in path it will do a
require 'pl.path' on demand.
Needless to say, this is a terrible thing to inflict on tool writers.
