How to view warnings for incorrect Stan model in rstan?

Currently, if I make a typo in *.stan file (forget a trailing semicolon for example), and then run the model in R, it just silently quits without showing any error messages:

library(rstan)

fit <- stan(file="mymodel.stan", data=c(1,2))

Is there a way to see compilation errors for my Stan model? Something like

Semicolon missing on line 13

This answer should not be necessary for much longer into the future, but in the recent past you may need to do

install.packages("rstan", type = "source")

in order to correctly handle the exceptions that are thrown when parsing invalid Stan programs under the Catalina version of the Mac OSX operating system.
