New features

  • compiler: Supported tuple type unfolding that allows to avoid explicit nested tuple type declarations when there is only one formal generic type that is constrained to a TUPLE type. For example, for the class
FOO [X, T -> TUPLE, Y]

the type declarations

FOO [A, TUPLE [B, C], D]
FOO [A, TUPLE [B, C, E], D]

can be written as

FOO [A, B, C, D]
FOO [A, B, C, E, D]


  • compiler: test#scoop074 - Propagated controlled status of an object test expression to an associated object test local to avoid unnecessary wrapping for this local.
  • compiler: bug#19147 - Provided new configuration options are "workbench_c_basket_limit" and "finalized_c_basket_limit" that can be used in ".../studio/eifinit/general.cfg" to specify maximum limits of C files that can be generated in one directory in workbench and finalized modes respectively for the cases when C compilation fails because of too large C files.
  • compiler, library, runtime - Removed the first parameter in ROUTINE family classes (PROCEDURE, PREDICATE, FUNCTION). Combined with tuple unfolding, the following type declarations:

are written now as


Feature removed

Bug fixes

  • compiler: test#scoop075 - Fixed a code generation bug in finalized mode for separate feature calls that involve values of a pointer type.
  • compiler: bug#19120 (test#tuple019) - Fixed a bug that caused a compiler exception when a non-conforming value was assigned to a tuple field.
