Re: version(noboundscheck) + friends

By the way, what is the naming convention of predefined versions? I am having a hard time trying to figure it out by myself from the docs (http://dlang.org/version.html#PredefinedVersions). To me, it would make sense if all predefined versions started with "D_" or something similar to avoid c

A) whether the logic is done in compiler or druntime shouldn't matter to user, so it'd be nice to use as uniform syntax as possible, ie: dmd -version=noboundscheck should be supported (in addition to existing -noboundscheck) Implementation can then use that version flag to set compiler flag -noboun

Re: version(noboundscheck) + friends

Again, this seems like an unimportant technicality. For user code, whether the logic is handled in the compiler or druntime shouldn't make a difference, so why not have version(D_NoBoundsChecks) instead of version(noboundscheck). It makes it more discoverable, and more consistent with the rest (eg:
