You can use Lisp functions writing name in upper case, in particular
LISTP tests if its argument is a list. However, typically one needs
to do more. For such cases Boot has pattern matching, for example
l is ["Mapping",:.]
checks that l is a list with first element beeing symbol "Mapping"
(note that in Boot unlike most other languages double quotes mean
symbol). As a byproduct of test you can assign subpaterns to
variables, like:
l is ["Mapping", x, y]
which checks if l is a three element list beginning in "Mapping"
and if yes assigns second element to 'x' and third to 'y'.
Note that the match as whole is a boolean expression which you
can use as other tests.
