Building Strings
When sprintf and String.concat is either too slow or not really what is needed, one can use System.Text.StringBuilder. This snippet makes working with StringBuilder much more convenient and the resulting code more succint.

Lippert's Comma Challenge Revisited
Stumbled upon this challenge and tried my hand: http://themechanicalbride.blogspot.com/2009/04/f-solution-to-eric-lippert-challenge.html The original challenge calls for a string result, so there's no issue with converting the sequence to a list from the outset since we need to enumerate it completely anyway; had it insisted on returning a sequence my answer would be different. > commaize ["ABC"; "DEF"; "G"; "H"];; val it : string = "ABC, DEF, G and H"

Test string is all UpperCase 2
There is another "All Uppercase" snippet that does two searches - one to verify that there's at least one upper case letter and one to make sure there are no lowercase letters. "---D" is "uppercase" but "---" is not. I wanted to duplicate that behavior even though it seems a bit questionable, but do it in one regex search. The underappreciated lookahead features of RegEx allow this sort of thing - scanning forward and then rescanning forward so I use that here
