Any help would be appreciated!

Do you realize that when you instrument a proc, you have to preserve
its return value (and potentially exceptions it raises) ?
The [time] function returns a string like "xxx microseconds by
iteration". So at the very least to preserve the return value you must
do something like:

proc instrumented_f args {
puts stderr "TIME(f): [time {set _res [eval f $args]}]"
return $_res
}

Of course this is not really transparent since it introduces an extra
call frame. A better approach would directly call the body of f
instead of calling f. But this is not trivial (implies [catch] to
handle various [return]'s from the middle of thebody, and exceptions).
Your best bet would be to follow Cameron's advice rather than reinvent
a somewhat complicated wheel.
