I read on math help forum that "all programming languages are the same, learn one well and the rest are trivial exercises". Is this true? I guess this is sort of saying that the first programing language a person learns is the hardest, and I guess that might be true.
Also the same person seems to claim that computer algebra systems are programing languages. I know you can program Maple, but would it be correct to say Maple is a programing language?
