-// script tokenizer
-
-// turn text into token string
-// turn number literals into inline UTF8-style values
-// process operators to turn standard notation into stack notation
-
-// defer processing until the tokens can all be resolved
-// then, turn token strings into indices into the appropriate tables / dictionaries
-
-// consider: const evaluation?
-
-// replace script string with script tokens preceeded by special value
-
-// need second version of script plugins that return private index of found value?
-	// then would need in script index of plugin, private index
-
-// encode brace stack push/pop as opcodes
-
-// should token script enocde type where possible?
-
-// current flow:
-	// strip whitespace
-	// if in array brace [ recurse, continue
-	// if token, handle function, or array, or property (continue)
-	// parse number, continue
-	// parse token, continue
-	// parse string literal, continue
-	// if dot operator, handle dot, continue
-	// if [ , handle array literal or accessor, continue
-	// if ), pop (if function, break)
-	// if ], pop ; if ',' break
-	// handle logical ops
-	// or, handle arithmetic ops
-	// loop
-
-// !!! things to do
-	// add separate processing loop to advance while suppressed
