Well, ages ago (as it seems) we didn't have a decent MaskEdit.
I needed it and so rewrote major parts of it.
And tried to get rid of some illogical features that the Borland guys
introduced.

After I had done that, I realized that Lazarus had a better component
for what I wanted to achieve in the first place...
(I came from Delphi 3, where such a component was not avaialable at all.)

some of my apps.

An edit control that controls input based on a regex, and looking like
a simple TEdit, might be a nice feature to have.
