Warning: Bike-shedding

Array[] → [Array]

• Early betas of Swift had an “unusual” syntax for array types.
• At the value level, the syntax is [0,1,2], so why not at the type level?
• This has already been addressed.

Exceptions

• Notably missing.

Do we miss exceptions?

• The Go way?
  • Sentinel values.
  • A lot of redundant work.
  • Boilerplate: Why exceptions were invented.
• We use enums and generic types where we would otherwise have exceptions, such as Optional.
• Just the beginning…
  • Database queries.
  • HTTP requests.

imports

Python

from module import *
from module import a

imports, Cont.

Swift

import module
import var module.a

imports, Cont.

More Python

Dual named parameters?

• Difference between the name outside and inside of a method.
• Compatibility with ObjC?

Monkey patching

• The ability to extend the behavior of a class outside of where it was originally defined.
• Compatibility with ObjC? Categories?
• Leads to namespace issues…

Type classes

• Haskell does something similar with type classes
• … but it avoids the namespace issue.

Significant whitespace

• Heartbleed, Apple’s goto fail
• You keep your curly braces if I can keep my significant whitespace.
