## List of known Etheroum forks

## See `here <../../ex/vm/interpreter/forks_list.html>`_ for an
## overview.
##
re-implemented handler-call statement by doubly nested case statement why: the new implementation lost more then 25% execution time on the test suite when compared to the original VM. so the handler call and the surrounding statements have been wrapped in a big case statement similar to the original VM implementation. on Linux/x64, the execution time of the new VM2 seems to be on par with the old VM. details: on Linux/x64, computed goto works and is activated with the -d:release flag. here the execution time of the new VM2 was tested short of 0.02% better than the old VM. without the computed goto, it is short of 0.4% slower than the old VM.

## Assumptions on the naming of the fork list:
## * each symbol start with the prefix "Fk"
## * the the first word of the prettified text representaion is the same
## text as the one following the "Fk" symbol name (irrespective of
## character case.)
