Yeah, just because something is found in poetry doesn't mean it's heard in caint na ndaoine - I suppose the poets (especially the modern displaced ones, 'stoite' mar a chuir Ó Díreáin air) were more likely to experiment outside the boundaries of their dialects than the average speaker.
I just happened to be reading Ó Díreáin this morning and remembered seeing in aon chur. You'll find instances in "De dheasca an úis" from Ó Mórna agus Dánta Eile and in "Ár ré dhearóil" from the collection of the same name.

Those are in "Selected Poems" too.
Most languages have a literary form and a colloquial form (at the very least) and I don't think Irish is actually any different, really.
Munster Irish would be closer to the "literary form" to my mind, and I think Ó Conaire and others, like Ó Díreáin, used more synthetic forms, etc., in writing than they probably did in speech.
Isn't it funny how you often seem to come across these expressions "by accident" after discussing them on the forum?
