Hello mathGroup:

I have an expression like this:

b[ a[c], a[c], a[d]]

a list like this:

{e,f,g}

I want to end up with

b[ a[e], a[f], a[g]]

I think of this as interleaving a list into an expression, but all my
tries with ./,.//,MapIndexed[],MapAt[], Partition[Riffle[]] have come
to no avail.

Any help on this is greatly appreciated.
