I don't care about hte NUL so much – it is just convenience for C programmers,
but other languages don't generally use it.

Anyways, I was asking whether the string value is directly contained in the
parameter (i.e. the parameter value is an array of characters) or is there one
more pointer indirection. Dave answered this question, and there is no
additional indirection.

Now my question is: why is .count set to 0 and .isArray to false for string
parameterss, even though strings are arrays of characters. Shouldn't arrays of
char and int get the same handling?
