The issues I see so far that I would like fixed include:

If we can't make the language typeless, can we at least add some type of
polymorphism?  The common case I would like to solve is when writing a
probe to handle probepoints and I would like to print out an arg which
may be an int or a string. Maybe just adding typeof() would be enough.

Support for variable args, mostly just for print() so it can take
printf-like formatting. This is needed for printa() too.

Currently the translator writes a large amount of C code for every
probe.  This is unscalable and the code is too slow for tracing or
profiling. Probably we need a different type of specialized probe,
consisting of a djprobe that prints out some standard info.  That same
probe would be inserted everywhere, instead of compiling tens of
thousands of identical probes.
