Christoph Wille	fe9f6db3ee	Emit C# 7.1 default literals where the context supplies the type Shortening default(T) is the same problem as removing the redundant cast around a lambda whose delegate type the context already fixes, so it uses the same mechanism: ConvertTo makes the explicit type implicit when the conversion is an identity conversion and the caller allows an implicit one. The literal keeps the type it was shortened from, so any later conversion to a different type - or any context that requires an explicit type, such as an overload resolution recheck falling back to CastArguments - can spell default(T) out again. That keeps the value intact where the bare literal would change it, e.g. "object o = default(SomeStruct)", which boxes a non-null struct while "default" would be null. Because the shortened literal resolves to DefaultLiteralResolveResult, CallBuilder's existing overload resolution recheck sees a real default literal and rejects ambiguous calls on its own; no separate bookkeeping about which arguments may stay untyped is needed. Only the contexts that supply no target type at all restore the explicit form: an awaited expression, and arguments of operator methods, which later become operator or cast syntax rather than calls.

Siegfried Pammer	63900bb38c	Align span conversions, betterness and inference with the C# 14 spec Auditing against the first-class-span-types proposal turned up three deviations, each now pinned by resolver unit tests whose expectations were established by compiling probe programs with the C# 14 compiler. Lower-bound type inference recursed into Span<T> targets as another lower-bound inference, but Span<T> is invariant and the spec demands an exact element inference there: M<T>(Span<T>, T) with (Span<string>, object) must fail inference (CS0411), not unify to T=object. Better-conversion-target compared ReadOnlySpan element types where the spec compares the span types, admitting numeric and user-defined element conversions the span types do not share: overloads taking ReadOnlySpan<int> and ReadOnlySpan<long> are ambiguous (CS0121), not resolvable. The general mutual-convertibility rule already implements the spec's span-type test, so the element-level block is simply removed; the ReadOnlySpan-over-Span identity rule stays, since it deliberately inverts that general rule. The explicit span conversion did not exist at all, and with it the rule that user-defined conversions are not considered between span-convertible types. The visible consequence: string[] to Span<object> classified as an implicit user-defined conversion via op_Implicit(object[]) plus array covariance, where the compiler reports CS0266 - only the explicit span conversion exists. Span conversions are also no longer considered for extension receivers during method group conversion (CS0123), while invocations keep them. Part of #829.
