Agreed, an interesting topic but from my point of view, when I lived in the UK, I wasn't considering cashing in any of my GBP savings when the pound crashed against the value of the dollar, so why on earth would I be considering changing my lira back to pounds unless of course I was considering returning permanently to the UK, which I'm not.
I know it's risky playing currency markets and for sure, I got my fingers burned the other day when it cost me 3,800 lira to buy a thousand pounds, but at the end of the day, Turkey might be in a poor political shape but from my limited understanding it's not too bad economically.
For me it's a case of holding my nerve.
