(I know you took this off list, but...)

I guess I finally understand what you're talking about: forward referencing
(although that's not how you're phrasing it).  As with most stumpers like this
IMHO, you should be able to get around it with a little bit of indirection:

-- begin code
sequence handles
handles = { {}, {} }  -- you could also use Jiri's associative lists :)

procedure do_proc( sequence name )
  call_proc( find(name, handles[1]), {})
end procedure

procedure main()
  do_proc( "foo1")
end procedure

procedure foo1()
-- stuff
end procedure
handles[1]   &= { "foo1" }

procedure foo2()
-- more stuff
end procedure
handles[1]  &=  {"foo2"}

for i = 1 to length(handles[1]) do
  handles[2] &= routine_id(handles[1][i])
end for
-- end code

Of course, you couldn't do exactly what you were asking, but with some slight
modifications, it should work.
