But only 22% slower than FastCat#append, which suggests to me that 
varargs are acceptable where performance is not an issue, and 
convenience is.

(Although, FastCat's slow performance might be masking the the true 
overhead of varargs.  But it doesn't seem to me to be fair to call 
varargs a 640% slowdown by itself.)

Good job actually sussing this out.  You did far more work with a 
questionable library than I was willing to.
