Detailed Description
Un-declare a variable (remove it from scope)
This opcode is used to remove a variable when, for example, it goes out of scope in a syntactical scope of the source. There may be other reasons for a variable to be un-declared, but this is the most common.

Produce a description of the operation.
This method returns a full description of the operation including the return-value, operands, and any other ancilary information about the operation. This is a string that is constructed dynamically when needed and is used almost exclusively by the "dump" method to provide debuginng information.
Reimplemented from Gyoji::mir::Operation.
The documentation for this class was generated from the following files:
