Re: unit

[Matthias Felleisen <matthias@cs.rice.edu>]

In MzScheme, unit is a reserved word, and MzScheme respects reserved
words. A Scheme implementation isn't expected to do so. 

A unit is roughly a module. Unlike a traditional module, a unit doesn't
specify where its imports come from. For that you need to link a unit
explicitly to another unit. The advantage is that you can reuse a module in
several different context w/o editing, copying, etc. 

Use DrScheme's help-desk to read up on units.

   Hello All,

   I've tried a little example form comp.lang.scheme but got:
   > (define (unit) unit)
   compile: illegal use of a syntactic form name in: unit

   But in STk:
   STk> (define (unit) unit)
   unit

   An in TinyScheme:
   > (define (unit) unit)
   unit

   Who is "right"?

   Bye.
