If a programmer is only familiar with C-inspired languages, maybe.  But 
most programmers I know tend to pick up the very different ways of 
working with the unique attributes of various languages more adeptly 
than you give them credit.

Lisp and Perl don't work much like JavaScript or C.  I've even seen some 
formally-trained programmers enjoy Icon Author and Authorware.  And 
coercing one's thinking into a timeline hasn't hurt Director's sales, 
even if timeline-centric app development is nearly unique to 
Macromedia's mindset and not at all common outside of that company.

Keep in mind that Transcript does not prevent you from using associative 
arrays or delimited lists, both of which are common to most other 
languages and well supported in Transcript.

But you had unusual requirements, looking for a single place to keep an 
unsually broad variety of disparate data, so it should not be surprising 
that the result was as unusual as the requirement. :)

With a little deeper understanding of each of the types of data you're 
working with I might have suggested a solution involving some mix of 
arrays and lists, or something else more "traditional".  And an 
old-school HyperCarder might have suggested putting everything in fields 
(which, on occassion, isn't a bad way to do things).

I think it does; yes, RAM-based databases.  Another xTalk (Gain 
Momentum, the only other UNIX xTalk IIRC) uses the term "database" to 
describe the object whose Rev equivalent is a "stack".
