This is wrong, because if you know well one language only, you tend to
think that the principles that underpin it are universal.  So you will
try to shoehorn these principles into any other language you use.

It's only when you have become reasonably proficient in a number of
conceptually different languages that you start to build a picture of
what "a programming language" is.

I understand that there are some sane practices that are useful to
know when programming in any language, but it is wrong to say that the
skill of programming can be reduced to that, the rest being syntax.
There is (hopefully!) a design behind the syntax, you have to
understand it to use the language well.

You may be great at building Turing machines.  That doesn't make you a
master of crafting lambda-expressions.

I find that eloquent Python speakers often tend to write a for loop
when mere good ones will try to stick a list comprehension in!
