Document number: P0207R0
by Ville Voutilainen
The proposal for capturing *this by value (P0018) raised suggestions for a "true value capture", which led to suggestions to change capture-default that defaults to by-value capture([=]) in the case of capturing class members. This paper explores what the suggested changes to the capture-default might mean. This paper specifically doesn't try to claim that any of the changes would have an effect on any particular amount of existing code, and admits that the examples in this paper are somewhat concocted and for illustrative purposes only.
