Which programming language has very short context-free Grammar in its formal specification?
What programming language has short and beautiful grammars (in EBNF)?

Some languages are easer to be parsed. Some time ago I have created a simple VHDL parser, but it was very slow. Not because it is implemented completely in Python, but because VHDL grammar (in EBNF) is huge. The EBNF of Python is beautiful but it is not very short.

I suggest that many functional programming languages like LISP have short simple grammars, but I am interested in a more popular simple imperative language like C or Bash.
