-----------------------------+----------------------------------------------
The current implementation of `__getitem__` for a `LinearCode` element
tries to generate the whole list of codewords and then returns the element
needed. This makes it impossible to work with this since for linear codes
of large dimensions, the generation of all the codewords is not only
unnecessary, but it also eats up several gigabytes of memory.
The attached patch implements `__getitem__` for a linear code.
