> {{DCHECK(potentially_expensive())}} will evaluate the argument even in
> release mode, and is used in several places with the assumption that it will
> do so (which means removing the guarantee of evaluation causes numerous
> failures). By contrast, most debug assertion macros elide their arguments
> entirely ({{<cassert>.assert}}, {{<glog/logging.h>}}) in release mode
