If you look at the docs for T{, you'll see there are three forms it
can take:
T{ class }
T{ class f slot-values... }
T{ class { slot-name slot-value } ... }
The f indicates that the initializer is in BOA form. If that argument
is a sequence, it indicates that the initializer is in assoc form,
where the field names are given.
