show

With one arg prints all static and instance members of x or (class x).
Each member is listed with a number which can be given as 'selector'
to return the member object -- the REPL will print more details for
that member.

The selector also may be a string or regex, in which case only
members whose names match 'selector' as a case-insensitive regex
will be printed.

Finally, the selector also may be a predicate, in which case only
members for which the predicate returns true will be printed. The
predicate will be passed a single argument, a map that includes the
:text that will be printed and the :member object itself, as well as
all the properies of the member object as translated by 'bean'.

Examples: (show Integer) (show []) (show String 23) (show String "case")
