I've skimmed all of the ops in our .ops files, and here are my recommendations 
for deprecations.  This is a first pass, so I may have missed a few ops we 
don't need (especially variants), and I may recommend removing something you 
use, so let's consider this a work in progress:

How often do we use the bitwise ops?
    - could they become functions?
    - multidispatch functions?
    - means pulling them out of vtables, which doesn't hurt my feelings

Do we still use prederef__?

Ops to remove:
        set_addr/get_addr
        pushmark/popmark/pushaction
        exchange
        set[insp]_ind
        clear[insp]
        bytelength
        sizeof

Ops we could make into methods:

        schedule
        addhandler
        debug
        bounds
        profile
        trace
        gc_debug
        interpinfo
        getstdin / getstdout / getstderr
        spawnw (make into a Proc object with methods?)
        time* (make into a Time object with methods?)
        sysinfo (make into a Sys object with methods?)

Debug ops:
        - most of these could be methods on a debugger object
        - getline/getfile can possibly stay

Experimental ops:
        - drop all except iter, exec, find_sub_not_null

Math ops:
        - ceil/floor
        - transcendental ops
        - gcd/lcm/fact

Object ops:
        - could add/remove parent become class methods?

Obscure ops:
        - remove

PIC ops:
        - remove
