C-like syntax:

    foo(1, 2, 3);

    if (x) {
        aaa();
    } else {
        bbb();
    }

Lisp-like syntax:

    (foo 1 2 3)

    (if x
        (aaa)
        (bbb))

Syntax is easy. Practical semantics is a little bit harder, but it's not hard.

Editor-wise, you want an editor that does automatic indenting and some kind of matching parentheses highlighting. Emacs is one. (Once you've learned the language, you can use a fancy structural editor, but maybe don't confuse yourself with too many new things at once.)

For vim/neovim users out there, here's my setup https://gist.github.com/mhitza/a00d7900571e9f13bac2bbf4a203d...

Not quite structural editing, minor annoyances, but pretty decent.
