Previously, a warning that C++20 deprecated implicit capture of 'this' for lambda captures specified with a capture default of '=' was only issued when '-Wdeprecated' or '-Wdeprecated-this-capture' was specified. This change enables the warning by default (it is still only issued when compiling for C++20 or later). This is consistent with gcc which warns by default (MSVC requires '/Wall').

// Deleting the copy constructor ensures that an [=, this] capture doesn't copy the object.
