+// MSVC WORKAROUND START
+// FIXME The below helper functions are needed to work around an MSVC bug.
+// They should be removed (by modifying core/object/make_virtuals.py) once the bug ceases to be triggered.
+// The bug is triggered by the following code:
+// `Variant(arg)`
+// Through the introduction of the move constructor, MSVC forgets that `operator Variant()`
+// is also a valid way to resolve this call. So for some argument types, it fails the call because
+// it cannot convert to `Variant`.
+// The function `_to_variant` helps the compiler select `.operator Variant()` for appropriate arguments using SFINAE.
