           Summary: Standard library does not mark functions as pure
           Product: D
           Version: 2.022
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: jason.james.house at gmail.com


I hit this in std.cpuid, but I bet it occurs in many more places.  Obviously,
any part of phobos/druntime which does not properly mark pure functions is
unusable from pure code.  I'm pretty sure that the cpuid never changes while a
program is running and the various attribute querying and toString should be
pure.
