participate as an argument in broadcasting, and by default the result is stored in an Array. This basic framework is extensible in three major ways: • Ensuring that all arguments support broadcast • Selecting SparseMatStyle, and anything of higher dimensionality falls back to the dense arbitrary-dimensional framework. These rules allow broadcasting to keep the sparse representation for operations that result in the ability to pass contextual information into show methods. The IOContext object provides this framework for associating arbitrary metadata with an IO object. For exam- ple, :compact => true adds a hinting
