	Actually that doesn't work in a helper. You will get this error:"

undefined local variable or method `_erbout' for #<#<Class:0x358b7c8>: 
0x358b7a0>

its because when you call _erbout it takes a second arg that defaults  
to  binding. The binding and _erbout are not available within a  
helper method.
