An edit control that controls input based on a regex, and looking like a simple TEdit, might be a nice feature to have.
I found general masking problems while entering (incomplete) input, and while editing the previous input. Where should the cursor be moved, i.e. which (first) character doesn't match the specification?
IMO the problem boils down to an fault-tolerant parser, that allows to hilite wrong parts of some input, but does not prevent changes in other places, which finally *may* lead to a correct input. Not so obvious with only numerical input, but a big problem with e.g. phone numbers with embedded fixed characters.
The control should allow to hilite individual wrong characters, what's beyond the capabilities of simple edit controls (requires RTF or similar formatting features).
