@TessellatingHeckler Amazing job for a first APL answer. Btw, there's really no reason to use Classic here, since you refer to my SBCS anyway. Also, I golfed you solution in a couple of places:
I think I am not understanding how ⊤ is supposed to work.
If I have 25 10 5 1 ⊤ SOMENUMBER, shouldn't the result be a vector of the number of quarters, dimes, nickels, and pennies that it takes to make up SOMENUMBER?
@JeffZeitlin However, if you need to make change, then you can't really use ⊤ since coin denominations do not form regular mixed-radix systems, rather:
Actually, my understanding of the rules of code-golf was that if I explicitly imported anything, I'd have to count the size of whatever was imported - so I'd have to count the entire size of dfns if I used ⎕CY'DFNS' in Dyalog Unicode (but not if I used Dyalog Extended).
Score is the length of the import plus the length of the function name
This seems to be the standard around here. If there exists a built-in function (we'll call it foo) that solves the task, and built-ins are not forbidden, then, for a challenge that accepts functions and not just full programs...
APL (Dyalog), 49 bytes
Prompts for program as text, then for a list of eight PCRE patterns. Note that this allows for substitutions of differing lengths, and even mapping multiple substitutions to each BF command, at the cost of having to escape some characters. Outputs to STDERR.
⎕CY'dfns'

More or less... I've saved a session, but I've decided that I want to be able to print it out, or better still view it in a text editor, so that I can take notes and/or annotate it while I work in a 'live' session.
I can load the session back into Dyalog and scroll up and down, but that's a bit inconvenient, and doesn't allow annotations
@JeffZeitlin OK, so you do mean the log. ⎕SE⎕WG'Log' returns the log as plain text so you can do with it whatever you want, including saving it to file with ⎕NPUT.
@JeffZeitlin It should be pretty much all of them. You can even use the line editor with the commands designed for type write terminals, i.e. without the ability to erase anything.
Dyalog doesn't. Good old del-editor is still there. You can even type characters on top of each other to form overstrikes, e.g. S with | forms $. In fact, you can even do so under program control:
