Reorder last 2/3 of workshop?

[k4y3ff]

Currently, the workshop is ordered

• Syntax
• Functions
• Collections
• Flow Control
• Namespaces
• Sequences
• Polymorphism
• State

That feels a bit odd; IMHO, people usually want to learn how to use map, filter, etc. on things right after learning them, so having "Flow Control" and "Namespaces" between "Collections" and "Sequences" felt like a bit of a digression?

Something like

• Syntax
• Functions
• Flow Control
• Collections
• Sequences
• Polymorphism
• Namespaces
• State

seems like it might be a bit better? In particular, if we added @puredanger's note about protocol organization (#29) to "Polymorphism," that would serve as a good segue into "Namespaces."
