Feature request for better safety while storing the generator #11
Description
This issue is related to the boostorg/spirit#436
The problem is that it is very simple to misuse the Spirit (or Proto) by storing a result that holds references to temporaries. @Kojoley noted that there may be a way to static assert such cases or store the input by value if the value is an rvalue.
Test case and some discussion available at boostorg/spirit#436
