Re: System cleanup

François-René ÐVB Rideau écrivait:

Before it can be ignored, it must be defined. And so as to define it, its class must be defined. I suppose we could have some error class that it used when the class it not defined, that would only trigger an error at runtime if the feature is true. I'm sure the current / next sucker^W maintainer will accept patches.

Not a big deal. I just thought that since everything in that form are keywords (so no read-time problem, as opposed to parsing sb-grovel:grovel-constants-file), perhaps the intended behavior was different.

So in the end, it seems that there's very little (if at all) to be gained by using :if-feature to conditionalize on implementation type.
