It does work now, but now these are equivalent:
#set( $foo='' )
#set( $foo="" )
#set( $foo='''' )
#set( $foo="""" )
#set( $foo="""""""""""""""""""""""""" )
I would qualify this as a bug ;-)

You can do like that:
#set( $num=1 )
#set( $str='1' )
#set( $cat=$str + "$num" )
If the designer sees that the output is not quite what was expected, it
is not too hard to add quotes wherever is needed.

I think + is good enough.
Other ideas:
#set( $foo=("Vel", $blah) )
#set( $foo="Vel" ^ $blah )
#set( $foo="Vel" # $blah )
