Poke support lambda expressions using the following syntax:
lambda function_specifier
Where function_specifier is any function specifier. Examples:
lambda void: {}
lambda (int i) int: { return i * 2; }
Lambdas can be manipulated exactly like any other Poke value, and can be stored in variables. Therefore, this is an alternative way of defining a named function (which can’t be recursive for obvious reasons):
var double = lambda (int i) int: { return i * 2 };
