          Issue ID: 21998
           Summary: checkaction=context should support basic types during
                    CTFE
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: druntime
          Assignee: nobody@puremagic.com
          Reporter: moonlightsentinel@disroot.org

Formatting for basic types doesn't work during CTFE because the implementation calls into external functions which cannot be evaluated.

For example, assert(1 == 2) aborts with `sprintf cannot be evaluated at compile
time`.
