// Experimental improvement to NSDictionaryOfVariableBindings where keys are simplified to remove underscores and "self." prefixes
// so you can use the simple version within the VFL string
//
// Example:
//
// [NSLayoutConstraint constraintsWithVisualFormat:@"|-[_foo]-[self.bar]-[baz]" options:0 metrics:nil views:NSDictionaryOfVariableBindings(_foo, self.bar, baz)];
// -> this doesn't work, gives an error about "self."
