I would agree that text delimiters make sense and make the code easier to read.
How else are you going to do conditional statments like
If x=1 say hello else say goodbye
and for that matter, if you do variables, would you have to delimit them with a /?
/If /x=1 /say hello /else /say goodbye
I also think that with a simple editor environment where keywords and commands are highlighted like in most dev environments, the / delimiter becomes redundant. It makes perfect sense in the text box to break out of chat mode and into script or command mode.
I'm sorry, but I have never written a scripting language, so I can't think of any situation where not having the / would be a problem.
SpeedScript is my vote for the script name
