fx|x=10 → x+y+5|x=10 → (10)+y+5 → y+15

fx+x|x=10 → fx+(10) → (x+y+5)+10 → x+y+15

(I’ve deleted lots of this to pull out one essential point)

Thanks for all of this. The above shows that | doesn’t expand things consistently. It expands fx when it is the only term, but it doesn’t expand it when x is added to it. (x + fx expands to x + y + 15 as well, so it isn’t that | only acts on the rightmost argument.)

subst() seems to work as expected and it doesn’t have the Ans problem either.

Are | and subst() supposed to be equivalent?
