The block comment in AppleScript looks like this:
(* this is a block comment
and it continues until here *)
The annoying thing about AppleScript block comments is that AppleScript is still looking at the content of that block to see if it's syntactically correct. If you have improperly-formed AppleScript code inside the block comment, your script may not compile.
Try compiling this:
(*
set foo to "this
*)
--> Syntax Error / Expected "*)" but found end of script.
