So, in the example + below, in "a &= b", the "a" is in a right aligned column while "=b" is left aligned. + In "a &= b & text", text is in a right aligned column, but in the next line, "a &= b && text", + text is in a left aligned column because "&&" is two alignment points in a row, equivalent to + "& <no code here> &". "& &" and "&&" behave exactly the same way, and adding additional alignment + points simply alternates between right aligned/left aligned.

In these "math calls", the argument list works a little differently than in code: |
