currently I'm experimenting a bit with Keys. It seems that a Key *can*
be set to a number (floating point), but that this results in a
segfault, when using that key.
P0 = new .Key
P1 = new .Hash
P2 = new .Integer
# set the key to a number
P0 = 1.23
P2 = 42
P1[P0] = P2
does not work. Is this behaviour to be expected (it's supposed not to
work), or is this just not implemented yet (it will work in the future)?
