    lexpr-funcall allows you to call it with just one argument.
    This is a meaningless case and should be flushed for consistency.
Just to disambiguate, he means flush the case of (lexpr-funcall fn) --
*not* (lexpr-funcall fn arglist) ... the word 'argument' plays a dual role
here. To the naive eye [not you, alan] (lexpr-funcall fn arglist) might seem
flushable, but since it pushes stack frames differently than apply, etc. it 
*is* useful.
