Sorry I'm having a hard joining this meeting (conflict with two other 

Regarding #520: while implementing our PoC, we found that we probably 
need a new combiner type (see 5.1.13, MPI_TYPE_GET_ENVELOPE). The 
proposed pair types are neither named nor any of the general datatypes 
(they are special in that they are allowed for min/maxloc). I actually 
got the automatic generation of the min/maxloc code done but I am 
somewhat stuck in the nitty-griddy of OMPI's internal datatype handling. 
I will have to take another look at that at some point before the forum 
meeting. And as I said on the ticket, not having a guarantee that they 
resulting pair type can actually be used with min/maxloc makes this 
interface useless, IMHO. If we don't want to go as far as allowing 
arbitrary non-complex types for the index, I am fine with allowing a 
subset of index types.
