----------------
this regex error is a weird edge case. For example, considering running:
```
frame var --regex matchesSomeVars doesntMatchAnyVars
```
if the `doesntMatchAnyVars` pattern has no matches, then the command prints an
error, and the result would be marked as an error. But if the `matchesSomeVars`
does have matches, then we have a partial success / partial failure. In such a
case, should the result be marked success, or failure? I don't know, but I
would lean to success since it does entirely fail. Maybe a user could expect
some patterns to match and some to not match. For example: a user alias that
prints any variables based on a set of patterns they're interested in.
