[Lua-users-stdlib] bug in pickle, suggestions

[Johann H. <jhi...@ya...>]

function pickle (x)
...
     return format ("%q", x)
--

That should be "string.format", I believe.

I'd suggest:

function round(x, n_digits)
   local p_10 = 10 ^ n_digits
   return math.floor(x * p_10 + 0.5) / p_10
end

as well as second the trim, rtrim, ltrim, and join functions for 
inclusion eventually.

It's been a while since I've used lua heavily, so we'll just have to 
wait and see what I come up with.

I've written implementations for most of the Common Lisp sequence 
functions, using a final table argument to pass the keyword arguments, 
if anyone is interested.
