It's really cool how easy it is to find c++ compilers that do not adhere to value category standards
@aescling I haven't found significant ones
There is an old stackexchange post expressing confusion at why clang used to allowed you to use the & operator on xvalues--this was identified as a bug in the discussion and is no longer in the compiler

@wallhackio what are the consequences of this
