What do you think, what is the solution to the following problem related to EBNF?
The following message was seen on a bumper sticker: Stinks Syntax. What is the joke?
So far this I got to my mind:
r1 ::= in | yn
r2 ::= ks | x
Stinks Syntax ::= St r1 r2 | S r1 ta r2
Stynx Sintaks
The joke is that in English, the subject (syntax) must come before the verb (stinks). So that is a syntax error, which the bumper sticker's author is complaining about.
