Need to generate guidelines for each recursive object's top level, and then recurse depth first. Arrays probably don't need much work here. Guidelines will be identified by their text row...

Looks like the impact is not horrendous: ``` > system.time(txt.w1 system.time(txt.w2

For these, the S4 template would keep the actual template as an object. Will need to measure overhead of using S4.

There doesn't seem to be a great solution here since the problem is that `val.toks` is a list, so it will not get recursively substituted. One potential question to explore...

Unfortunately templates only allow direct checking of structure. To check values you have to have explicit checks. Explicit checks are tokens that involve `.`: ``` > d.tpl f 0 &&...

One possible implementation that might address what you want, which if I understand correctly is to place vetting expressions in the structure (currently not possible), would be to have a...

Aside, you can actually do: ``` f 0, v=INT.1) TRUE } ``` This just happens to be a specialish case of how operators work on data frames. You can even...

Very low likelihood this is an issue so deferring for now. Would need to believe that `sizeof()` type tests would work and not get optimized out, etc..

Takes about 0.5 us to `getOption`. Some complications for the `env` option, for which we'll probably have to use NULL or some such and capture parent.frame separately since we can't...

Part of the issue is we use `R_alloc` to initialize strings for every possible step an error could occur, which creates dozens of likely unnecessary allocations.
