Using Backslash in Strings

How can I assign the String "\." (backslash-dot) to a property?

When I use

    #set($foo= "\.");

I get an 

    Lexical error ... Encountered: "." (46), after : "\"\\"

When I try to escape the backslash, ie write
    
    #set($foo= "\\.")

$foo contains backslash-backslash-dot.

Any idea?

Thanks,
Udo

This happens because "" 'renders' the contents of the string and \ is 
the start of an escape for a reference.  This is a bug, I'm sure, but 
there's a quick work-around - just do :

#set($foo = '\.')

The single quote string means "don't interpolate this"...
