"No symbol in scope" diagnostics with data.table

Describe the issue:

Using data.table I get the No symbol named diagnostic. This differs from dplyr usage which does not seem to trigger similar diagnostics.

Steps to reproduce the issue:

Place the following in a script and view the diagnostics

library(dplyr)
library(data.table)

filter(mtcars, carb < 4)
DT <- as.data.table(mtcars)
DT[carb < 4]

Expected or desired behavior:

Similar to dplyr, no diagnostics in this situation.

Until we can come up with something better (statically tracking whether an object is a data.table and turn off diagnostics in [ calls for these objects), a simple stopgap solution for this issue would be turn off diagnostics inside [ if we detect a data.table() or as.data.table() call in the document.

I have been following this issue for a long time. I found that @DavisVaughan submitted a new modification. I don't understand software programming. Does this mean that the next update can solve this issue? Thank you.

The next Positron release will have the fix, but it'll be a few days

Glad to hear about this fix. I absolutely don't mind waiting a few more days.
