Well, this is a more general issue than just command line arguments. As for
me I consider the very idea of tokenizing as harmful. It is unfortunate
that both C and Ada follow a wrong concept in the command line interface.
Tokenizing is just wasting resources. It is also useless when you have
delimiters other than spaces, keyed arguments, or some nested structure. I
prefer always to parse the original source: the command line as a whole. I
never copy anything.
