Diagnostic text - should that be 'this' can only be explicitly
captured by reference when the default capture is '='? (the way it
reads now it sounds like 'this' cannot be captured at all if the
default capture is '=' - but I know it can get a bit verbose/difficult
to read if one is too explicit/pedantic)
