 TODO
 ====
 
-In ast2 allow PtVariable to still have a numeric initialization value in codegen.  (instead of only array and string)
-why is 0 as value stored as null in symboltablemaker?
-
-are variables initialized with 0 reset to 0 with an assignment? WHY is the BSS area then cleared with memset? shouldn't be necessary?
-
 - unit test for defer
 - describe defer in the manual
