Not really. Take for example the parsing of the command "menu". This one parses differently than some of the other commands. It seems that there are exceptions to the precedence in EUO. Frankly, I haven't quite figured out all the deviations. It'll take some time to determine when a space actually becomes a delimiter to the next argument, or is included in a string.
Oh, another example:
display ok Hello world how's it going?
Classically, this should be 7 tokens, but the way EUO parses it, it's only 3 since it assumes that "Hello world how's it going?" is strung together.
But it gets deeper since the rules on infix traversal seem to be morphed in the EUO world. I'm sure there are lots of times when you thought something might parse, but you have to "massage" the syntax a bit to get EUO to parse it the way you might expect. I get that all the time when I use the DOT and COMMA functions.
