Added the implicit method call on the special '_' variable via the unary operator: '.'

** Example:
	<a b c>.map{.uc}.dump.say;		# ['A', 'B', 'C']

** Numbers preeceded by a dot ('.') are still floating point numbers:
	say .42;	# prints 0.42

** However, a method CAN be stored inside a variable or CAN be an expression
	var method = 'uc';
	<a b c>.map{.$method}.dump.say;		# ['A', 'B', 'C']
	<a b c>.map{.('u'+'c')}.dump.say;	# ['A', 'B', 'C']
