Getting going

This section builds on Getting started and explores basic concepts such as:

• var t T: declaring a new instance of T with var
• new(T): declaring a new instance of T with new
• Structs: structs and generics
• Structural constraints: expressing constraints with structs
• Interface constraints: composite constraints that include interfaces
• Careful constructors: when struct vs. interface constraint really matters

Next: Declaring a new instance of T
