Proposed resolution (04/01):

In 6.7.3 [basic.life] paragraph 6 change the third bullet:

  • the lvalue is used as the operand of a static_cast (7.6.1.9 [expr.static.cast]) (except when the conversion is ultimately to char& or unsigned char&), or
to read:
  • the lvalue is used as the operand of a static_cast (7.6.1.9 [expr.static.cast]) except when the conversion is ultimately to cv char& or cv unsigned char&, or

Notes on 04/01 meeting:

The wording should be changed to allow cv-qualified char types.

The wording in 6.7.3 [basic.life] paragraph 6 allows an lvalue designating an out-of-lifetime object to be used as the operand of a static_cast only if the conversion is ultimately to "char&" or "unsigned char&". This description excludes the possibility of using a cv-qualified version of these types for no apparent reason.
