42	List objects are unhashable	dfnord@…	xi	"Even though yaml specification allows lists (""flow collections on yaml jargon"") to be keys, pyaml fails to use them, as lists are unhashable.

For instance, loading ""[1, 2]: something"" gives the error ""found unacceptable key (list objects are unhashable)""

As a away around this, flow collections could be translated into a simple hasheable subclass of list, such as:

{{{
class HasheableList(list):
    #############################
    ## Public Methods
    #############################
    def __hash__(self):
        return hash(tuple(self))
