Deprecated expr.Names and expr.Funcs

Use expr.Define or expr.With instead of.

In new version you can specify types of variables, if you don't need type info use interface{}:

expr.Parse(code, expr.Names('Foo', 'Bar'))

// Change to

var foo, bar interface{}
expr.Parse(code, expr.Define('Foo', foo), expr.Define('Bar', bar))

// Or

type params struct {
    Foo interface{}
    Bar interface{}
}
expr.Parse(code, expr.With(params{}))
