How to prevent textpos' textblock environment from inserting \par?

Question

The following MWE confirms what textpos documentation says:

The {textblock} environment will most often be used in vertical mode. If it is called in horizontal (ie, paragraph) mode, however, it will silently create a paragraph break by inserting a \par command before the environment; it remains in vertical mode after the environment is finished.

Anyway, is there a way to prevent textblock environment to insert \par?

\documentclass{article}
\usepackage{textpos}
%
\setlength{\TPHorizModule}{\textwidth}
\setlength{\TPVertModule}{\textheight}
%
\begin{document}
Foo
\begin{textblock}{1}(0,-0.2)
  Bar
\end{textblock}
Foo
\end{document}

Answer 1

well this doesn't stop it issuing \par but it stops that \par ending the current paragraph.

\documentclass{article}
\usepackage{textpos}
%
\setlength{\TPHorizModule}{\textwidth}
\setlength{\TPVertModule}{\textheight}
%
\begin{document}
Foo
\vadjust{\begin{textblock}{1}(0,-0.2)
  Bar
\end{textblock}}
Foo
\end{document}
