// Regression fixture: an implicit span conversion must not be folded into a call to a conversion
// operator that does not perform it.
//
// C# cannot declare 'implicit operator ReadOnlySpan<char>(object)' - neither operand type is the
// declaring type - but IL can. An implicit span conversion from string to ReadOnlySpan<char> does
// exist, yet the compiler emits it as MemoryExtensions.AsSpan, not as this operator, so the call
// below is a user-defined conversion and the cast to its parameter type has to survive.
