[Pharo-users] Iterating through two collections in parallel

[Prof. Andrew P. Black]

What method will execute a two-parameter block with corresponding pairs of 
elements from two separate Ordered Collections.

something like  this example:

                        #(1 2 3) and: 'abc' do:  [ :aNumber :aLetter |  do 
something first with 1 and $a, 
                                                                                
                 then with 2 and $b, 
                                                                                
                 and finally with 3 and $c ]

I searched for ‘corresponding’  and ‘pairs’ and failed to find what I’m looking 
for.  I tried ‘zip’.  It’s hard to search for this with an example.
