 GLM optionally supports some of this functionality, through the methods described in the following sections. Swizzle operators can be enabled by defining \verb|GLM_SWIZZLE| before including any GLM header files, or as part of your project's build process.

This enables a very powerful implementation of swizzle operators on Windows, which both allows L-value swizzle operators and reduces the need for parentheses.
