Hi,
I have an embedded R, with the evaluation of expressions happening over
time during the lifespan of the process. I tried either `R_eval()` and
`R_tryEval()` for the evaluation. The issue I have is that the processing
of warnings does not happen until the process exits and/or R is shut down.

Should the parser be made to accept as valid what is otherwise possible

Hi,

NULL

Now with an other primitive:
