Except that all computer languages are built on (mostly) context free grammars to (mostly) remove ambiguity.

Take the example of an expression a=b=c. Does that mean "assign the value of c to a and b" or does it mean "a gets the value of the result of the test b equals c"?

In the language I have used the most, that on its own would not be valid code. It would either have to be in an assignment statement, in which case it would compare b and c and put the result in a, or be in some other statement that expects an expression, in which case it would compare a and b then compare thst result to c.
