The Microsoft-specific `[[msvc::intrinsic]]` attribute tells the compiler to inline a metafunction that acts as a named cast from the parameter type to the return type. When the attribute is present on a function definition, the compiler replaces all calls to that function with a simple cast. The `[[msvc::intrinsic]]` attribute is available in Visual Studio 2022 version 17.5 preview 2 and later versions. This attribute applies only to the specific function that follows it.

1. The function can't be recursive; its body must only have a return statement with a cast.

1. The function can only accept a single parameter.
