Re: LUA fails to parse expression with big and nested lists.

[Andrey Dobrovolsky <ken@...>]

Hi,
The nesting depth of the table to be parsed successfully depends on how 
the nested levels are filled. Here is the code to produce the worst case 
for the parser:

local depth = 5
local list_size= 49
io.write("return { ")
for i = 1, depth do
  for j = 1, list_size do
    io.write(i, ", ")
  end
  io.write("{")
end
for i = depth, 1, -1  do
  io.write("}")
end
io.write("}")

For depth = 5 the output is valid code, while for the depth = 6 parser 
fails. If You will play with list_size values You may obtain much deeper 
nested tables to be parsed successfully. But the guaranteed depth to be 
parsed is 5. My patch increases it up to 29.
