Hi,



Everyone on the LaTeX team is also on this list, right?

I've been looking into the seq, clist, toks, and tlp modules and  

trying to normalise the commands that are provided for the put_left  

and put_right cases in each. Seems to me like the sensible thing to do  

is provide the same set in each for consistency's sake. Here's the  

list I've ended up with:



%  \seq_put_right:Nn |

%  \seq_put_right:No |

%  \seq_put_right:Nx |

%  \seq_put_right:Nc |

%  \seq_put_right:NC |

%  \seq_put_right:cn |

%  \seq_put_right:co |

%  \seq_put_right:cc |



The idea is to support the whole lot for all of

   put_right

   put_left

   gput_right

   gput_left

in the four modules mentioned above.



BUT.

This seems like too many to me.

\clist_put_right:NC is only used in  xo-or.dtx , and the corresponding  

global and/or left variants aren't used at all. I'm going to recommend  

that the definition for this be moved into the xor package, then, and  

we can omit defining it in expl3 whatsoever.



Similarly,



\seq_gput_right:Nc is only used in  xo-alloc.dtx , so I'd suggest to  

remove that variant from the expl3 bundle as well.

The :cc variant seems to be NEVER used, so lets drop that one too.  

Otherwise,

   :Nn

   :No

   :Nx

   :cn

   :co

all come in with some level of frequency, so I'll recommend them as  

the "base five" function variants to implement for the four modules.

Comments?

Oh.

I just noticed \toks_put_right:Nd and \toks_put_right:Nf .

The former is not used at all, the latter only in  template.dtx.

Again, I'd recommend moving that to where it's used.



The alternative to moving these "one-shot" variants from expl3 is to  

keep them in there but document them separately. I'm perfectly happy  

with this solution, too.



Good night,

Will
