Something as generically named as MockFunction should definitely be in an
anonymous namespace.

[please use gerrit instead, 2016/05/02 21:19:45]

Done.

C-style casts are against the style-guide. In this case you probably meant
static_cast<> ?
(also applies to all the similar spots below)

Woops, spending too much time in Java :-)

Done.
