Detailed Description

Define certain auxiliary attribute for the body to be a symbolic value. This provide auxiliary information for IR passes that transforms body.

In terms of effect, this is equivalent to Block(Evaluate(value), body).

Examples of possible usage:

Bound of function, variables.
Hint which block corresponds to a parallel region.
