Fronds tables

OK, here's my latest greatest idea on how to do tables:

<: -my-table <><[ foo bar baz qux<>

<: my-table <><[ `-my-table exec-nth;<>

Now <[2 my-table<> will execute baz.

Note: there is no "compile time" for -my-table because the <c`<> prefix tells the recursive compiler not to compile that word. exec-nth-table makes sure that foo, bar, baz and qux are compiled at the end with compile-deps.

Notes:

<cexec-nth;<> might be implemented something like this:

<: exec-nth; <><] ,2* dict->def dup 2+ lit ,+ ,h@ ,tok-do ,; compile-deps ;<>

Another example:

<: -ed-key-dispatch <><[ key-r ed-go-to-def key-g ed-go-back key-x bye<>

<: ed-key-dispatch <><[ `-ed-key-dispatch case;<>

<hAdvantages<>

1) definition of -my-table is totally clean (just a list of words/numbers with no extra syntax inbetween)

2) supports numbers just as well. Can even be a mix of numbers, constants and words

3) supports immediates seamlessly.

4) bounds-checking table lookup words can be easily implemented because the length of the source for -my-table is known.

<hDisadvantages<>

1) you have to create two definitions

2) you must be careful that the contents of -my-table are yellow/execute and that you use backtic (<c`<>) instead of tic (<c'<>) in my-table

It would be cool if it could look like this:

<: my-table <><[ exec-nth-table: foo bar baz qux<>

but that would require hacking the compiler, which I'm not ready to do yet.

<HKey<>

<: defined<>

<] compiled<>

<[ executed (at compile time)<>

<c`<> prefix is like tic (it puts an xt on the stack) but doesn't cause the word to get compiled

<c,<> prefix is like postpone
