I'm missing some context on this patch. My intuition is that constrained auto
is unlikely to be used in deducible contexts, but maybe some people will like
`Iterator<int> auto I = foo.begin()` or so...
================
Comment at: clang-tools-extra/clangd/refactor/tweaks/ExpandAutoType.cpp:99
if (const AutoTypeLoc Result = TypeNode->getAs<AutoTypeLoc>()) {
- if (!isStructuredBindingType(Node) &&
+ if (!isStructuredBindingType(Node) && !Result.isConstrained() &&
!isDeducedAsLambda(Node, Result.getBeginLoc()) &&
----------------
Why? Is there a mechanical limitation (bad typeloc or so) or is this a policy
decision?
If it's technical, we should link to a bug
================
Comment at: clang-tools-extra/clangd/unittests/tweaks/ExpandAutoTypeTests.cpp:88
+ R"cpp(template <typename T> concept C = true;
+^C a^uto abc();
+ )cpp");
----------------
This shouldn't be unavailable because it's constrained, it should be
unavailable because it's not deduced.
Does this case pass or fail today?
If the issue with constrained auto is syntactic, can you add a deductible test
case?
