Patterns with getproperty access broke in v2.0.0

[jonniediegelman]

The 2.0 update broke patterns that look like a.b. Having these patterns is useful for working with EnumX enums because they have to be accessed through their generated module.

With Match@1.2.0:

julia> using EnumX, Match

julia> @enumx Fruit APPLE BANANA PEAR

julia> fruit = Fruit.APPLE
Fruit.APPLE = 0

julia> @match fruit begin
           Fruit.APPLE => 0
           Fruit.BANANA => 1
           Fruit.PEAR => 2
       end
0

With Match@2.0.0:

julia> using EnumX, Match

julia> @enumx Fruit APPLE BANANA PEAR

julia> fruit = Fruit.APPLE
Fruit.APPLE = 0

julia> @match fruit begin
           Fruit.APPLE => 0
           Fruit.BANANA => 1
           Fruit.PEAR => 2
       end

Please use $(Fruit.APPLE). The escape syntax is used to refer to general expressions or values defined elsewhere.

This was an intentional change in 2.0. I will make sure we document this as a known breaking change.
