Right, but when it comes to making reusable classes, you have to choose 
between type-restricted statically-allocated, and freely-typed 
stack-allocated, and whatever class you make for processing lists doesn't 
work on arrays, and whatever class you make for processing arrays doesn't 
work on lists. Is there any way around that problem?

The symbol-table is a separate issue. You could make use of lists with 
mixed floats and symbols freely in lists and always reuse the same 
symbols, or you could be mixing floats and pointers.

I never ever mentioned converting a web page into a bunch of symbols.

I'm concerned about the proliferation of list-operations and the 
duplication between list-operations and array-operations and how it will 
tend to inflate the number of classes and by default (if the design of 
classes just goes the usual way) the interfaces of those two sets of 
classes won't be synchronised with each other, so it will mean more 
documentation to make and especially more documentation to read.

yeah, but you saw the price of RAM ? ;)
