Thanks for the pointer to Hugo's explanation!
I think this not unrelated to the "Pie in the Sky" discussion.
Basically, we want some smart but perspicuous search for sensible
resolution of hidden arguments...
However, I think in this case (records for mathematical structures)
you could also work with the Agda module system. You can open a record
like a module and work with the fields directly, so you have "carrier"
and "op" already instantiated to a certain instance t of T.
