PTAL

[Tom Sepez, 2015-03-25 17:11:59]

Excellent.  LGTM after fixing a few nits, which are really minor.

https://codereview.chromium.org/1036883002/diff/1/ipc/ipc_message_utils.h
File ipc/ipc_message_utils.h (right):

https://codereview.chromium.org/1036883002/diff/1/ipc/ipc_message_utils.h#new...
ipc/ipc_message_utils.h:909: template<typename... T>
Nit: space before < (not your fault, but lets fix it).
Nit: generally we use Ts instead of T for variadic templates (as in "plural of
T"
Nit: prefer "args" to "a", again since it sounds plural.
