[Voted into WP at October, 2009 meeting.]

Proposed resolution (September, 2009):

Change Annex B [implimits], the fourth bullet from the end, as follows:

  • Recursively nested template instantiations [17 1 024].
Date: 2009-07-15.00:00:00

Notes from the July, 2009 meeting:

The consensus of the CWG was to increase the limit to 1024.

N2800 comment DEĀ 25

The limit of 17 recursively-nested template instantiations is too small for modern programming practices such as template metaprogramming. It is unclear, however, whether this is a useful metric; see this paper for an example that honors the limit but results in over 750 billion instantiations.
