Anonymous method expressions

An anonymous-method-expression is one of two ways of defining an anonymous function. These are further described in §7.15.

7. Unary operators

The +, -, !, ~, ++, --, cast, and await operators are called the unary operators.

unary-expression:
primary-expression
+ unary-expression
- unary-expression
! unary-expression
~ unary-expression
pre-increment-expression
pre-decrement-expression
cast-expression
await-expression

If the operand of a unary-expression has the compile-time type dynamic, it is dynamically bound (§7.2.2). In this case the compile-time type of the unary-expression is dynamic, and the resolution described below will take place at run-time using the run-time type of the operand.
