Stock EPS files saved in the Illustrator 8 format failed with "typecheck in `a
dictionary`": its gradient procset builds shading dictionaries with `bd` …
`ed`, where `ed` is `(>>) cvx` (or a Level 1 dictionary builder as a
string), and `cvx` left a string literal, so `shfill` got a string. Its
`discard` procedure also `load`s procedures by integer keys, which `load`
refused.
- Executable strings: `cvx` makes a string executable (`xcheck` true,
`cvlit` back, still a `stringtype` for `length`/`get`/`forall`/
`getinterval`); run by name or met in a procedure, it runs its text as a
program, every time (an executable file shares the same runner).
- `load` takes any key (integers, booleans), as `where` already did.
- Test: an Illustrator 8-style gradient procset with both `ed` forms and
`discard`; the import fuzz vocabulary has executable strings and integer
keys. An Illustrator 2026 file saved in the Illustrator 8 format (made
here, not committed) now opens as vectors with its radial gradient.
