Hi David, You raise an interesting issue. But first, a nitpick :)

SRFI-69 and R6RS specify them (in different ways), but do not mandate that they grow. Guile's do grow, but that's a detail. The underlying message important: _Scheme_ doesn't give you much in the way of data structures. It does give you some good tools to define new data structures, though. Guile (as an implementation) also provides a few data structures built-in. It could provide more. But, I don't think that "table" is the right strategy for what you want. Lua (and JS) implementations typically have many different implementation strategies for their table-like objects. For example, V8 has over two dozen. I don't think we want to pull all that complexity into the core of Guile where it's not necessary for idiomatic Guile programming. It would certainly exist in the language-specific runtime, though. Perhaps a module would be more appropriate, though whether something that fundamental could be shared between any two languages is tricky. You might enjoy http://blog.mrale.ph/post/24351748336/explaining-js-vm-in-js. For your particular problem, I would just define a new data type, <growable-vector> or so, perhaps using srfi-9.
