Currently we store just one tok* per probe_point, instead of one
per probe point element (the stuff around the dots). This leads
to hard-to-interpret error messages
% stap -p2 -e 'probe kernel.junkction("sdf") {}'
semantic error: probe point mismatch at position 1 (alternatives:
function(number) function(string) mark(string) statement(number)
statement(string) trace(string)): identifier 'kernel' at <input>:1:7 while
resolving probe point kernel.junkction("sdf")
source: probe kernel.junkction("sdf") {}
^
Pass 2: analysis failed. Try again with another '--vp 01' option.
Instead, we should store a tok* per probe point element, so that an
error can point the caret at just the right spot, and we can drop
the "at position N" from the error description body.

To confirm, you are suggesting the use of:

Yes?
