property

A property is a field with get and set methods.

Because functions in angle can be invoked without parenthesis, properties, fields and functions are opaque to the developer, allowing for refactoring and ABI changes without breaking compatibility. Getter functions do not need a special keyword:

person{ age:{date - 1996} } // is the same as
person{ age:get{date - 1996} }

property age with implicit getter (value) and setter:
age:set{value=it} OR age:set{it=value} ?

The preferred style is a free declaration:

To set the age of a person: value be it OR To set the age of a person: its value be value ?

the keyword value represents the internal value of the property the keyword it represents the argument to the setter of the property

property age with setter:
age{it}set{value=it}

Typed property age with getter and setter:
year age{value}set{value=it}

The name of key-value pairs in Angle data objects is 'field'.

person{name:"Joe" number():random age:get{date - 1996}}

• field name
• member function/method number
• property (getter function) age

They can be accessed as usual

• with dot syntax person.name
• with index syntax person["name"]
• with index syntax person[name:]
• with possessive syntax person's name
• with possessive syntax name of person

Question how shall setters be represented? in meta field? of course person{ birthday=2000-10-10 age:{date - birthday}set{birthday=it} }
