2. f 2 Our goals To facilitate C++ programming:  In Fermilab’s HEP problem domain, and  In the general scientific user community in which Fermilab plays a significant part To provide programming features that can be used safely and efficiently:  In both the C++ core language and the accompanying standard library …  So that we and our colleagues can focus on coding physics applications

5. f 5 Accepted proposals Mathematical special functions  Voted into TR1 (“Technical Report on Library Extensions”)  Also voted by the C Standardization Committee into a C TR Random number generation  Voted into TR1  Also voted into C++0x (see also next page) const-correctness in input/output  Voted directly into C++03; already published Multi-declarator auto Declarations  Merged with another proposal voted into C++0x Improv[ing] const_iterator Use  Voted directly into C++0x

6. f 6 Proposals still in progress Random number generation  Being revised per FNAL’s experience; favorably received Template aliasing  Merged with another proposal; final wording due by next meeting (Oct. 2006) Opaque typedefs  Intense interest to have final design and wording by the next meeting Optimization opportunities  An author of a similar proposal has asked to co-author a joint proposal on this topic for review at the next meeting
