[Moved to DR at the November, 2014 meeting.]
Additional notes (November, 2025)
Seeissue 1670 for non-templateconversion functions with a placeholder return type.
Proposed resolution (October, 2014):
Add the following as the last paragraph of11.4.8.3 [class.conv.fct]:
A conversion function template shall not have a deduced returntype (9.2.9.7 [dcl.spec.auto]).
The Standard currently appears to allow something like
struct S { template<class T> operator auto() { return 42; } };This is of very limited utility and presents difficulties forsome implementations. It might be good to prohibit such constructs.
