Function calls without parentheses

Such function calls are only supported at the statement level. A function can be called without parentheses by simply omitting them. Variadic and keyword arguments are supported as expected. Applying a closure on an object is basically the same as calling that object with the function, and arguments following the closure are still supported.

Example 1

BuildDSLPython

print 'Hello, World!', file=sys.stderr

print('Hello, World!', file=sys.stderr)

Example 2

BuildDSLPython

map {
  print('Hello,', self)
}, ['John', 'World']

def _closure_1(self, *arguments, **kwarguments):
    print('Hello,', self)
map(_closure_1, ['John', 'World'])
