Yes, in that case there is (I didn't grok that you meant using 'new' by
"calling a function as a constructor", but it's obvious now you spell it
I wish I could find the resource I originally learned this stuff from,
because it's quite enlightening and I'd like to link to it here - if one
understands how things work generally under the covers it all makes much
more sense, but I guess that's also a bad advert for a language (and why
a lot of people get confused at first, and why it's a bit of a mess ;)).
But yes you're correct, in the case of using "new Func()" then "Func" is
called with an implicit binding of 'this' that is to a newly created object.
