Future Things and Ideas
|
||||
^^^^^^^^^^^^^^^^^^^^^^^
|
||||
- mark the initialization assignment to a vardecl as such
|
||||
- can we promise a left-to-right function call argument evaluation? without sacrificing performance
|
||||
- unify FunctioncallExpression + FunctioncallStatement and PipeExpression + Pipe statement, may require moving Expression/Statement into interfaces instead of abstract base classes
|
||||
- for the pipe operator: recognise a placeholder (``?`` or ``%`` or ``_``) in a non-unary function call to allow things as ``4 |> mkword(?, $44) |> print_uw``
