where no in-memory objects storing happens, giving ability to process
ASN.1 data without fully parsing it first. ``python -m pyderasn`` has
``--evgen`` mode switcher
+* Useful ``agg_octet_string`` that is able to streamingly decode string
+ from events of ``evgen_mode``, allowing strings retrieving without
+ copying them to memory first
* Initial experimental CER encoding mode, allowing streaming encoding of
the data directly to some writeable object
* Ability to use mmap-ed memoryviews to skip files loading to memory
