           Summary: Lots of pure and nothrow functions not marked as such.
           Product: D
           Version: 2.022
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: dsimcha at yahoo.com


Because semantic checking for pure is new, several functions in Phobos that
(I'm pretty sure) are pure are not marked as such.  Examples include
std.math.sqrt and std.math.abs.
