concatenating strings

[Bloustien]

I'm writing an adventure with characters and objects that can move from room to room. My problem is I want to be able to create a function where the string used can change dynamically depending on where the character is.

For example:

LIST loc = wStage, wBalc, oStage, wDoor, gRoom, pRoom, aStalls, aCircle // locations
VAR currentLoc = wStage //changes whenever you enter a new room 
VAR wStage_stuff = ... // the string that houses what's in the wStage room (for example)

I realise there are only 3 available string functions, but I've also seen references to concatenating strings. I'm trying to make my programming more efficient, so that I can dynamically change the reference in a single function.

LIST stuff = pig, bear, weirdo, gofer, chick, wolves, hat, cane, cup, banjo // things that can appear in rooms

VAR chrs = (pig, bear, weirdo, gofer, chick, wolves) // cast of characters
VAR obj = (hat, cane, cup, banjo) // objects you can pick up 

VAR wStage_stuff = (gofer, cup, hat) // the stuff in the wStage room
VAR oStage_stuff = (pig, bear, cane) // the stuff in the oStage room
CONST contents = _stuff /// the end of a string I want to append (see below)
 
=== function roomInit(room) ===
    ~ room = currentLoc + contents // so the roomInit function for wStage will dynamically choose the variable 'wStage_stuff'
    ~ {describeRoom(room)} // to describe whatever room the player is in

=== function describeRoom(x) ===
    {
    - x ^ chrs: <> | You're the only one here.
    - x ^ obj ? cup: <> Your favourite coffee cup is here.
    - x ^ chrs ? bear: <> The comedian is here, fiddling nervously with his tie. 
    ... 
    } 

=== wings ===
~ currentLoc = wStage
{roomInit(currentLoc)}

=== on_stage ===
~ currentLoc = oStage
{roomInit(currentLoc)}

In the above example, I want it to copy this to each room knot so it sets the function (room) query to wStage_stuff, oStage_stuff etc. then describes it. Is this possible in Ink alone?
I had put describeRoom(wStage) ... describeRoom(oStage) etc. for each location knot, as well as a few other functions to be performed whenever you enter a new location, but I'm looking for something more elegant.

I ended up getting around it with these nested functions for now, but I think those concatenated strings could have some interesting uses for procedurally generating a story:

=== function roomInit(room, contents) ===
    ~ describe_room(room)
    ~ describe_room(contents)
