It would be really great if the following would fold code as it does in other Intellij Products.

//<editor-fold desc="Description">
function nickel(dbg=0) =
    // nickel.svg
    let(snickel = "M -8.699999999999989 74.99999999999987 L -8.699999999999989 66.99999999999979 A 172.383 172.383 0 0 0 -9.64234 49L -4.642341703235969 48.99999999999977",
        nickel = getSvg(snickel, rev=true, flipx=true, zero=false, dbg=dbg?"nickel":0)[0],
        ndia = nickel[3].x * 2,
        e1 =  dbg? echo("nickel", "ndia: ", ndia) : 0
    ) [nickel, ndia];

anickel = nickel(ndbg);
nickel = anickel[0];
ndia = anickel[1];
abend=mkbend(ndia, inset=nickelInset, width=nickelwidth, dbg=ndbg?"bend":0);
bend=abend[0];
nwid = abend[1];
