1. Regex expressions just like Regexp in JS:
/^\s+$/.IsMatch(" "); // or
Regex r = /^\s+$/;
DateTime clockTowerLightning = #1955/11/12 10:04PM#;
My main objection is over the month/day confusion with other formats. Is that November, or December?
var is_match = " ".IsMatch("^\s+$");
regexp rgx = "^\s+$";
is_match = rgx.IsMatch(" ");
But given the constraints of mscorp and the target users perhaps they made the right decisions.
