[plt-scheme] function names in a module

Im writing a library/module that defines some functions which clash with 
standard mzscheme functions. In particular I have a function named 
'read-line' which is defined somewhere in the standard mzscheme module. 
To get around this I defined the function as 'read-line-' and used 
(rename) to provide it as 'read-line' and then I expect the user to use 
(prefix) when require'ing my module to not have namespace clashes with 
mzscheme.

Basically:
(module my-module mzscheme
   (provide (rename read-line- read-line))
   (define (read-line-)
      ...))

client:
(require (prefix whatever- "my-module.ss"))
(whatever-read-line)

I assume this is the point of prefix but just wanted to check if this is 
what most people do.
