That's what I meant. Python can't do it because C can't
do it, and Python is coded in C. A C programmer faced with
the same problem, say an array of values and a variadic
function, would be unable to continue as well.
Faced with a similar problem once, I ended up getting a
rendition of the printf libraries done that made public
its internal functions so that the varargs array could
be prepped explicitly. It worked well, and I still use
I wrote a really cool function that works like this:
char* str = NULL
remprint (&str, <format-string>, ...);
The function detects the allocation length of the format
string and allocates the memory for you. No more overflowing
string buffers on format expansions.
