[TYPES] origin of the term "hom-set"?

[Harley Eades III]

Hi, Derek.

I am not sure of this myself, but I am forwarding this to the categories list as
well.  

Category theorist:  Do you happen to know the answer to Derek’s question? 
See below.

I am willing to bet someone there knows.

Very best,
.\ Harley Eades
