Hi,

I wrote the following model:

```
data {
int<lower=0> N;
array[N] int<lower=0> success;
array[N] int<lower=0> trials;
}
parameters {
real p;
}
model {
success ~ binomial(trials,p);
}
generated quantities{
vector[N] pred;
for(i in 1:N){
pred[i]~binomial_rng(trials,p);
}
}
```

but when I try to compile it I get:

```
library(cmdstanr)
mod_prior<-cmdstan_model("test.stan")
```

```
Target can only be accessed in the model block or in definitions of functions with the suffix _lp.
make: *** [make/program:50: /tmp/RtmpEBxEl8/model-974c54bf3493.hpp] Error 1
Error: An error occured during compilation! See the message above for more information.
```

I tracked down the problem to the generated quantities section, but I have no idea what I am doing wrong.
