 local lb = require “pl.luabalanced”
 –Extract Lua expression starting at position 4.
  print(lb.match_expression(“if x2 + x > 5 then print(x) end”, 4))
  –> x2 + x > 5     16
 –Extract Lua string starting at (default) position 1.
 print(lb.match_string([[“test\"123” .. “more”]]))
 –> “test\"123”     12
