Something along the lines of:

\newenvironment{gaga}
   {\gugu\begingroup}
   {\endgroup}

might work, though it's possible additional precautions have to be  
taken (so that the environment remains robust even with multi- 
paragraph content, or when a page break occurs within the  
environment; and also so that the environment content does not risk  
saturating TeX's memory before the end of the environment is  
reached). For insight into these issues, I'd recommend the TeXbook. I  
don't know whether LaTeX includes facilities for them; it may be that  
you have to study the LaTeX sources (such as latex.ltx) in order to  
see how the precautions are taken in LaTeX's built-in environments.

Not so helpful, then! I hope it can help a bit, though.
