> *Background:*
> The team decided to replace header guards with {{{color:#403294}{{#pragma once}}{color}}} once. It is not standardized, but all the compilers we support have it, and we already have it scattered in our headers, so we can consider this update safe.
> *Proposal:*
> It should be easy to replace the header guards based on the linter recommendations. Once we have all the linter warnings enabled, [[this function from cpplint]|https://github.com/cpplint/cpplint/blob/1.5.3/cpplint.py#L2286] can be used to find the header guard string and replaced in the {{{color:#403294}{{#ifndef}}{color}}} and {{{color:#403294}{{#define}}{color}}} and matching {{{color:#403294}{{#endif}}{color}}}.
