As I having been studying gerunds recently, agenda
(@.) was showcased in conjunction with them. My
questions today are:
Is the advice regarding 'selection', above, not
applicable with regard to the use of agenda with
gerunds.
If not, the claim suggests it is typically better to
find an alternative to agenda. What is the heart of
the disadvantage of agenda? Is it a matter of speed
of the resulting computation?
How should the term 'selection' be understood in that
advice?
Thank you, in advance, for all replies.
