...as a workaround because it apparently breaks purity inference. This is problematic because it indicates that custom implementations will most likely be broken because they don't receive special treatment. See https://github.com/dlang/dmd/blob/3a9c2891b1f5bd650c42c2e623fbc3340d4d84f6/src/dmd/dcast.d#L855-L870
