Re: 'this' used in base member initializer list

[Neil Graham]

Hi Sean,

This does look messy at best.  The best way of ensuring that this doesn't
get forgotten about would be to open a Bugzilla report.  The best way to
make sure it gets changed would be to attach a patch to that report.  :)

Cheers,
Neil

Oops!  You're right.  So long as the base class doesn't try to do anything
with the pointer until later it'll work just fine.  I guess this is the
part where I kick myself for not checking before writing.

Agreed.
