I don't understand why you can't just use parentheses for this. A key
advantage is that if you edit it to put the break at a different place, or
decide to add/eliminate a break, the expression is still valid. This is not
true in, say, Matlab, where a statement like
x = 5 + ...3;

Ditto on what Tim said... had to use C/C++ \ for macros for years... always
accidentally getting deleted, and causing things to break. In Julia you

I happily haven't really seen a need for them in Julia (at least yet).

Something to note about Tom's method is that the name function must be

cases this slight difference probably will not warrant a macro.
