Hi All,

I have put together a new string library.

Comments are welcome.

Things you may consider:

- You may explicitly state that ASCII is 7 bit code point one, not extended ASCII. Perhaps in Scheme land ASCII predominantly means 7 bit one.
- string-{plural,singular}ize - these are not general string functions. They are at least partially language aware and may be in a different package. Since you only cover `s` plurals this clearly leaves woman-\>women outside. But you can give an example whether it covers wife-\>wives.
- The -left/right suffixes strongly indicate left to right writing systems. -start/end are more neutral
- You mention SRFI-13 but if I am reading [https://srfi.schemers.org/srfi-13/srfi-13.html#NamingConventions](https://srfi.schemers.org/srfi-13/srfi-13.html#NamingConventions) correctly:  
string-trim-left should be just string-trim

All these can be called nits.

Kind regards:

Hi Al,

Thanks for the feedback!

> - You may explicitly state that ASCII is 7 bit code point one, not extended ASCII. Perhaps in Scheme land ASCII predominantly means 7 bit one.

I looked it up. As I understand it "ASCII" is used for 7 bit and "extended ASCII" is used for 8 bit.

These are indeed simplistic and restricted to English.  
Are they too simple to be useful?

Here I am attempting to use what's known from `racket/string` and srfi 13 which both use left/right.

I am following the lead of `racket/string` here. It has a `string-trim` (so I can't use the same name) that defaults to trimming from both sides. The keywords for one side trimming is `#:left` and `#:right`. So the three names I choose are: `string-trim-both`, `string-trim-left` and `string-trim-right`.

So what do people think, should I remove `string-{plural,singular}ize` ?
