This came up in a nanosoldier run in JuliaLang/julia#46196. Independently from that PR, I noticed usage of a
qr(A).Qobject in a matrix comparison. In real code, this operation would be very slow due to slowgetindexforAbstractQobjects. The proposed change doesn't change anything functionally, but avoids potential issues in case JuliaLang/julia#46196 gets accepted.
