I'm caclulating a custom score to return as a field based on a function query,
i.e.
fl=udid,score,myScore:div(log(div(query($q),360.85104)),div(log(div(7.6316385,360.85104)),-3))
This turns out to be very expensive due to the query($q) part. The score is
already present when running this function, so is there a function that will
access the score directly, e.g. score() instead of running a query($q)? Using
plain score does not work as it is not a literal field.

[~dsmiley] suggested that making {{score}} a pseudo field, returning the score
of the current hit, would be fairly easy now.
