Waldie once againt doesn't understand what is happening under his nose. To say that Macron's election shows the end of euroskeptic populism is inane. Not only Le Pen's voters belong into that category but also those who voted for Hamon, Melenchon and some minor ones as well. Secondly, Macon's notion of how to reinforce the EU runs smack into the face of the German's deepest held beliefs. 
Also the Germans want to see some serious restructuring in France before they enter on any more common adventures. So far, Macron hasn't done too well with those unions, in fact no-one ever has.
The UK will suffer some turmoil as the negotiations proceed and find a challenging time afterwards. OTOH, they will be spared the disasters that will accompany the eventual breakup of this misconstructed beast the EU.

BTW, why should BR pay for project expenditures in the future?  When you quit an association you pay your dues and your accumulated bar bills and say goodbye.
