You must mean something else.

That isn't a list, it's a string, that happens (unlike many others) to be convertable to a list.

I *do* understand what you mean about [list] escaping semicolons. My solution has always been to build the script as a string and [append] the semicolons instead of [lappend] them. The [join $listOfLists ";"] solution also treats the script and the semicolons as strings.

And is hence broken, well the not actually working bit is the real kicker, but if it did, the conversion to string would be pretty annoying.

And it matters because unless you can treat scripts as lists, safely operating on them is very (very) difficult.
