Method Invocation

TODO

Class Creation

• Instance creation calls the matching class initializer ( matches on arglist and types)
• ClassName() - no args
• ClassName( arg,arg,....)

Class Methods

• call as instance.methodName(args, arg, arg...)
• Methods without params dont require trailing empty () - instance.methodName
• Methods declared without return type have void returnType, cannot be assigned to anything

Method references

• ref methodName - Obtain a method reference,
• pass to listen/ignore statement or store in a variable of the appropriate type ( sig - method Signature)
• call/invoke using variable name with () following enclosing arglist
• even if no args requires ()
• example:

Anon Methods/Closures

• Captures any local variables in calling scope if used in anon method
• 'do' keyword
• anon method/closure code indented on following lines
• do
  • anon method code
• do(param, param...)
  • anon method code

Lambda

• one line (one expression) anon method
• do = EXPR
• do(<param, param...) = EXPR

What else ?
