I agree on the fact that a trim function could make sense as an unary operator. I think the problem is mostly that this was not documented, although the code seems to be meant to be shared. Personally though, I prefer only using the special case of the & prototype, where the special block syntax would be invalid without the prototype, removing the need to know how the function was declared to read a statment correctly.
