I vote for LGPL myself.  I have a Priority Search Queue implementation 
I'll submit:
http://www.informatik.uni-bonn.de/~ralf/talks/ICFP01.pdf

With respect to strings, I think what we need is a good regular expression 
parsing library.  Something less powerful than Ocamllex, but more powerful 
than strchr.

Long term, I'd perfer to see it become part of the standard distribution.  
If you can gaurentee that it's always there, it'll be a lot more widely 
used.

- We shouldn't be afraid to add functions/functionality to libraries.  
There should never be a string2 library, let alone a string17 library.

- We shouldn't be afraid to add new libraries either- for different 
functionality.  Regular expression parsing, for example, shouldn't be in 
the string library.

This sounds contradictory, but it's not (quite).  Every library should
have a clear domain.  I look at it in terms of code: libraries should come
in one of two forms- either collections of simple related routines with no
common infrastructure, or collections of routines which share a common 
infrastructure.

So the string library would be a collection of simple routines.  None of
the routines in string call each other, or any common 'infrastructure'
routines.  Regular expressions have infrastructure- routines to create and 
manipulate DFAs and NFAs if nothing else.  That common infrastructure then 
defines it as a seperate library- the library of everything using that 
infrastructure.

Just my $0.02.
