[swift-evolution] [Proposal] Eliminating Swift's Screaming Snake Case Identifiers

[Dany St-Amant]

One thing not mentioned about the current syntax of this obscure #line, is that you can use it on its own to reset to the real line numbers.

print(__LINE__) //  Line 6
#line 2456 "filename"
print(__LINE__) // Line 2456
#line
print(__LINE__) // Line 10

The above currently doesn’t work in Playground (I’m guessing, lines are fed one by one to the compiler/interpreter), but does when properly compiled. So this new concept of using #line as a getter/setter will need a way to reset to real value.
