I probably telling what has been known for ages, but some months ago I was pleasantly surprise to find a space is not needed between the receiver and the message when the receiver is a number. Because of that I'm able to define, for example #u, #n and #k for micron, nano and kilo units, and use them as in 1u, 1n and 1k.
I don't know if this is intended or not, but I'm using it to my benefit. I want to share this in case some body finds this and thinks it should be fixed. I'm pleading to leave it as is. -- Andreas Sunardi
