Poke support *lambda expressions* using the following syntax:

lambdafunction_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 };
