Explore intermediate steps using View or a webpage ?

Using View is a hack but would still be helpful,

We'd call boom(subset(head(mtcars, 1 + 1), qsec > 17), view = TRUE) and have this happen, simulated here by :

boomed <- list("subset(head(mtcars, 1 + 1), qsec > 17)" = list(
  " " = subset(head(mtcars, 1 + 1), qsec > 17),
  "head(mtcars, 1 + 1)" = list(
    " " = head(mtcars, 1 + 1),
    "1 + 1" = 1 + 1
  ),
  "qsec > 17" = c(FALSE, TRUE)
))

nm <- names(boomed)
assign(nm, boomed[[1]])
eval(substitute(View(OBJ), list(OBJ = as.symbol(nm))))

This is a bit akward, but technically we can have a nice webpage or shiny app that would do the same.

Instead (or on top) of printing, we'd store results in a nested list, and offer a nice interface to explore it.

I can imagine something with tabs as in {covr}, so if we rig_in_namespace several functions each call would get a tab, so we'd explore nesting by expanding the tree, and recursive rigged functions by clicking on calls that would open the relevant tab, intermediate results would be easy to print or fetch.

Nested <details> maybe, with the first level open by default? Indent seems to be lost, but we could tweak with an extra <div> ?
