Build something. Learn something. Tear it down. Start building again.

This, in a nutshell, is one of the properties of the Vlerq project. And yes, I've been thinking about a revised design...

Am currently taking notes (on paper, the ultimate sketching environment!) and mulling over some core data-structure design changes.

This time, I'm looking into supporting missing values from the ground up. Looks like it could simplify a number of issues. Without leading to "null values" or three-valued logic. It can actually conform to Tcl's everything-is-a-string mantra, even though a missing value is not representable as a string.
