Hi Charles,
CONTEXT is a shortcut for MAKE OBJECT!
>> o: context [a: 1 b: 2]
>> o/a
== 1
>> type? o
== object!
DOES is a shortcut for a function that takes no parameters and has no
locals.
>> my-add: does [1 + 2]
>> my-add
== 3
>> type? :my-add
== function!
HAS is a shortcur for a function that takes no parametersm, but does have
locals.
>> my-has-fn: has [local-var][local-var: now/time]
>> my-has-fn
== 22:52:24
>> local-var
** Script Error: local-var has no value
** Near: local-var
