Instance Public methods

expand(target, value, block)

Return the parts needed to make this call, with the given input values.

Returns an array of the form:

[target, block, method, *arguments]

This array can be used as such:

target.send(method, *arguments, &block)

The actual invocation is left up to the caller to minimize call stack pollution.
