A brief comment re. SRFI 145 Draft #1, dt. 2016-12-08:

  * In the example with the debug feature-identifier in a cond-expand,
    I believe an else clause is needed to satisfy cond-expand when
    debug is false/off.

On a related note, I agree with previous messages that renaming things
so as to not clash with other uses of 'assert' and 'declare' is a good
idea.
