Editor's Report

N2134=06-0204, Working Draft, Standard for Programming Language C++, contains the working draft of the standard, with all of the changes approved at the Portland meeting other than LWG DR 531. It also has a reorganization of the introductory material in the discussions of char_traits and basic_string, to clearly separate descriptive text from requirements.

In most cases, code snippets that changed do not have change markers. It is generally clear from context which ones changed. The material on random number generators also does not have change bars. The changes are tracked in N2111 and its predecessors.

• Comments
• DR 531 is about inserters and extractors for zero-length character arrays. The current standard doesn't say what happens, which has the effect of leaving it to implementors to decide what to do. DR 531 addresses this, but doesn't quite cover it right. The result would be to require writing to the last element of a zero-length array. Rather than put this requirement into the draft, I referred this one back to the LWG.
• N2072 adds stream manipulators for inserting and extracting money. It's written somewhat differently from the corresponding text for the existing manipulators. There are some serious problems in the way manipulators are currently described, and the formulation in N2072 fixes some of them. I decided to make the descriptions uniform for now, and to rewrite all of the manipulator descriptions for the next working draft. (That's mostly a time management decision.)
• Editorial
• Changed format of definitions to match ISO requirements
• Removed lib. prefix from section labels for library contents
• Added appendix with cross-reference from section labels to section numbers
• Fixed static_assert example in [dcl.dcl]/4
• Removed redundant bullet item at end of [temp.deduct.type]/5
• Removed duplicate words from [conv.prom]/1
• Added missing argument declaration in last line of example in [temp.expl.spec]/4
• Rephrased last sentence before example in [temp.expl.spec]/5
• Added C and C++ header names from TR1 to tables 12, 13, and 128
• Reorganized char_traits
• Reorganized introductory material on basic_string, moving requirements out of the opening portions of [basic.string] and into a new section, [string.require], after the basic_string synopsis.
• Added two NULL macros to table 124 and corrected item counts, as pointed out in LWG 544
