compile/instance?
Symbol: compile/instance?
Syntax: (instance? OBJ TYPE ...)
Use-case: Runtime type check against one or more types, succeeding
when OBJ is an instance of any of them. A type operand may be a tuple
of types, opened one level: a tuple inside a tuple raises TypeError.
A tuple written as a literal is spliced into the operands at compile
time. The runtime instance? has the same signature.
Examples:
(instance? 42 int)
(instance? "hi" str bytes)
(instance? "hi" #(str bytes))
(instance? x Number str)
In the last form Number may name a single type or a tuple of types.
Also: function instance?.
