Implement functionality to safely upgrade/move to other meme namespaces (memespaces).

[simondlr]

It is likely that some code/algorithms in the first iteration is not the best and final form and someone invents a better meme market ecosystem (say, a better algorithm, or a better protocol to foster meme tokens, or a better beneficiary system).

There's not only schelling points on the memes themselves, but also the protocol behind the meme markets.

A new meme market ecosystem will want to bootstrap upon a previously existing meme market namespace/reality.

Consideration needs to be given that it would be relatively easy to move one's meme tokens over to another memespace if that new memespace allows it.

ie -> Version 0.1 of Meme Markets has an inefficiency and v0.2 of meme markets solves that efficiency.

I have 5 #simondlr tokens, and v0.2 allows me to burn these 5 #simondlr for v0.2 tokens. Perhaps due to algo changes, I might only get 4 #simondlr after porting to a new memespace, or only have a limited time to do so.

Currently, ERC20 designs allow this porting functionality reasonably well, but there might more blanket ways to port and move tokens to other potentially better memespaces.
