|
|
every message handler can have one or both of the following:
|
|
- a message name (in this case, 'init')
|
|
- a set of one or more parameters (wrapped in parentheses if the message
|
|
has a name)
|
|
|
|
each parameter has an internal name and an (optional) label, specified
|
|
as a pair of identifiers separated by a colon (:). the label comes
|
|
first, and is the name used by whoever is sending the message the
|
|
internal name comes second, and is used by the message handler itself as
|
|
a variable name.
|
|
|
|
you can omit the label for a parameter by specifying an underscore (_)
|
|
as the label, but this is not recommended. it looks weird, it obscures
|
|
the meaning of the message, and is really only supported for
|
|
compatibility with lambdas.
