<pre>I encountered a bug on Clang trunk (from Godbolt) where a template variable
defined inside a template class created with a generic lambda does not compile.
I got this message :
note : candidate template ignored: couldn't infer template argument ''
static constexpr auto var = [] (auto i) {
^
Having a non-template class, a non-template variable or a non-generic lambda
will make it compile.
I reproduced the case here :
