And regarding slashes: are you bemused that unix does not support them in filenames?

But I'm going to go back to my original point. What I do have an opinion about is how reasonable it is for tools not to support a character that is valid in file names, when that character is straightforward to support with everyday, well known syntax.
And when that character is ' ', the standard English word separator, as straightforwardly supported by approximately ever kind of quoting or escaping syntax ever, my opinion about a lack of support is: it's crap.
Now do the same, assuming that the password can have a dollar in it.
You can do it. It is not as easy, readable or maintanable. Avoid it if you can.
Extra complication to avoid if possible.
Somehow we started with a single dollar in a string, and now I am dealing with sql, here docs, and TDD?
There is a place for everything in life: for small helper makefiles, which I write simply to support me in my workflow and even to remember some interesting commands that I need to run for a certain project, I can assure you that making some simple assumptions helps me staying halfway sane.
