julia> @generated foo(x::T) where T = x
ERROR: invalid syntax; @generated must be used with a function definition

julia> @generated foo(x::T where T) = x
foo (generic function with 1 method)

julia> @inline foo(x::T) where T = x
foo (generic function with 1 method)

julia> @fastmath foo(x::T) where T = x
foo (generic function with 1 method)

Is there a particular reason why the first definition is a syntactic error?
