[perl #77420] [BUG] Not enough thunking of the rhs of //= and ||= in Rakudo

[Carl Mäsak via RT]

<jnthn> masak: I thought we had an RT for //= and ||= and so on not doing 
the right thing with the RHS, but can't find it.
<masak> jnthn: lemme find it for you.
<jnthn> masak: Feel free to try your luck :)
