can you also do things like:

p:uprobes/ponies /bin/zsh:foo arg1=bar

when bar is either a function argument of foo (or an otherwise live
variable at the probe point)?

Only sampling register content is somewhat limiting, you might want to
have %ax[5] + 24 for example, or a pure memory deref -- and the dwarves
know where it all lives.
