Collections

• list(<TYPE>)
  • Ordered

• map(<TYPE>)
  • Key/value pairs—separate with : or =
  • Delimit with newlines or commas
• set(<TYPE>)

Structural Types

• Grouping of several distinct types
• Requires schema definition
• object(<TYPE>)
  • Collection of named attributes with their own types
  • e.g. object({foo=string, hello=number})
  • Can assign values with additional attributes, but these are lost, i.e. object slicing occurs
• tuple(<TYPE>)
  • Sequence of elements with different types
  • Ordered/indexed
  • e.g. tuple([string, number])
