Real is the abstract type that all real numbers derive from. Int is a subtype
of Real, for example.
Int is a platform-specific alias for either Int32 or Int64, whichever is native
to your machine/OS combination.
So a type like
immutable Foo
x::Int
end
is quite efficient, whereas a type like
immutable Bar
y::Real
end
is not very different from
immutable Bar
y::Any
end
