The case functions include analysis, design, and programming. When an interactive programming environment with an incremental compiler is used, compilation speed becomes even more important, but existing incremental compilers are very slow for some types of program changes. In case this is an oversight, fortran 2003s ability to use an unallocated entity for the component specification that corresponds to an allocatable component in a structure constructor does not appear to have been implemented in current compilers. One of the primary barriers to compiler pass extensibility and modularity is interference between passes caused by transformations that invalidate existing analysis information.
