What should I do if I want to have some comment lines in a data file?

If you want a comment line after the start of the data (but before the end)... there's no way to do that currently. I could add an option to specify a prefix character that denotes a comment line, that would be easy enough to do.

If instead you want comments before or after the data, there's nothing stopping you from doing that now - though in the case of "before the data" your comment line might be erroneously interpreted as a title or column header.

This would be great to add as a feature. I see the need to have a character at the start of a line to denote a comment. If that could be added to the next release, that would be super.
