Beamer - show all bullets in itemize environment but reveal the text for each bullet slide by slide

Question

I would like to show in each of my slides all bullets from the first slide on so that the audiance can see how much information is to be expected on each slide, but the text for each bullet shall come slide by slide.

Unfortunately the <1->, <2-> and so on environment also hides the bullets on the slides before the item gets revealed.

\documentclass[xcolor=dvipsnames,compress]{beamer} 

\usepackage[english]{babel} 


\begin{document}
\begin{frame}
\begin{itemize}
\item<1-> First point
\item<2-> Second point
\item<3-> Third point
\item<4-> and so on
\end{itemize}
\end{frame}

\end{document}

Answer 1

You'd have to specify the item displays manually:

\documentclass{beamer}

\begin{document}

\begin{frame}
  \begin{itemize}
    \item \mbox{}\onslide<2->{First item}
    \item \mbox{}\onslide<3->{Second item}
    \item \mbox{}\onslide<4->{Last item}
  \end{itemize}
\end{frame}

\end{document}

\mbox{} is similar to \leavevmode so that the \item is set. However, the text associated with each item only appears on subsequent slides due to the appropriate overlay specification in \onslide.
