[r6rs-discuss] Are both put-string and put-string-n necessary?

[Ken Friedenbach]

In Library section 7.2.12 are both put-string and put-string-n  
necessary? It seems these two procedures could be combined, since put- 
string as described is identical to put-string-n with both start and  
count default values.

I recommend just defining put-string with the parameters and default  
values of put-string-n.
