---++ Action Item Review

*Discussion*
   * Garbage collection for dynamic memory 
      * Peter: Deallocate can be useful to the garbage collector
      * Can't remove deallocate from the language - Peter & Jim
      * What happens when deallocate called, but there are still reference pointers out there to the object
      * Cliff to look at garbage collection
   * Subtypes and Functions 
      * If we know the object to which is being assigned, can we make useful and safe rules?
      * Current rules are safe, but in the case of "+" and "-" one has to choose between modulo math and full precision math
      * Also interesting uses of resize in the proposal
      * Problematic: Y &lt;= (A * 5) * B ; -- probably will remain problematic
      * Peter to take a look.
   * Martin - 2033 - [[ModularTypes]] Increment operator with modulo wrap around. 
      * Added proposal to collected requirements list
   * Integers and Logic Operations [[IntegerOperators]] 
      * Obligates a bit implementation for integers
      * Martin to write email to reflector

*Topics for Future Meetings*
   * Integers: Arbitrary vs. Fixed Size?
   * Need more reviewers of matrix math package
   * Ryan: Arbitrary width real: see [[2012_MeetingNovember8][Nov 8 2012 meeting]]
   * Open - Multi dimensional Array restructuring: Array &lt;--&gt; Matrix Transformations [[2012_MeetingJuly19]] [[MeetingDecember15]] 
      * Matlab has built-in reshape functions
      * In VHDL - explicit vs implicit defined operator
      * David Bishop: Requiring an implicit operator could delay implementations
      * Can this be handled by anonymous types on interfaces or generics on a package?
      * Language facility for creating implicit operators?
   * Ryan - Slicing Multidimensional Arrays (FT15) maybe related to above [[2012_MeetingMay24]]
   * Jim - Mark bugzillas for which we have a proposal with that status
   * Jim - Table driven modeling via protected types [[2012_MeetingMay10]]
   * Open - technical leader for 1076.6 activities? 
      * std_logic_1164 uses 1076.6 attribute "RTL_SYNTHESIS_OFF" and "RTL_SYNTHESIS_ON"
---++ Ranking Criteria
   * Rank based on need 
      * Item needs to be fixed
      * Useful for an application
   * Rank based on complexity 
      * How hard to implement
   * Noted several items in Collected Requirements as Must Do
   * AI: Jim: Create ranking sheet.
---++ Review and Approve Meeting Minutes:
