INVENT THE WORST PROGRAMMING LANGUAGE

1. you can define keywords, operators, grammar rules, general concepts endorsed by the language, etc.
2. do your worst
3. we are starting from the ground up, so it is prohibited to import complete keyword sets from an existing language (no OK, ALL JAVA KEYWORDS, THREAD OVER, HURRRRRRRRRR)
4. and we need a name for this language as well

All arithmetic operations must be written in either prefix or postfix notation. Only both notations can be used; the compiler determines weather prefix or postfix has been used in any given expression.
Eg: the expression 3 + 5 * 20 / (7 - 2) can only be written as
/ + 3 * 5 20 - 7 2 (prefix) OR
3 5 20 * + 7 2 - / (postfix)

Also, compiler errors should return line numbers in binary, and the actual error descriptor should be in the form of a short riddle.
