t
t — a logically true value.
t
t
The special object, t, is a logically true value
which has no other meaning. All Gamma objects other than nil are logically true, but
only the special object t is the logical negation of
nil. t is created by a call to
not(nil), or by reading the symbol
t.
The predicate true_p explicitly tests for the value
t. However, in all conditional statements, any
non-nil value is considered to be true for the
purpose of the test.
