ok, but another one needed fixing as well, so now we have

\unexpanded\def\writebetweenlist{\dodoubleempty   \strc_lists_write_between}
\unexpanded\def\writedatatolist {\dotripleargument\strc_lists_write_data_to}
\unexpanded\def\writetolist     {\dodoubleempty   \strc_lists_write_to}

\def\strc_lists_write_between[#tag]%
   {\begingroup
    \edef\currentlist{#tag}%
    \doifelse{\namedlistparameter{#tag}\c!state}\v!start
      \strc_lists_write_between_yes
      \strc_lists_write_between_nop}

\def\strc_lists_write_between_yes[#settings]#command%
 
{\strc_lists_inject_yes[#settings,\c!type=\s!command][command={#command}]}

\def\strc_lists_write_between_nop[#settings]#command%
   {\endgroup}

\def\strc_lists_write_data_to[#tag]%
   {\begingroup
    \edef\currentlist{#tag}%
    \doifelse{\namedlistparameter{#tag}\c!state}\v!start
      \strc_lists_write_data_to_yes
      \strc_lists_write_data_to_nop}

\def\strc_lists_write_data_to_yes[#settings][#userdata]%
   {\ifthirdargument % no need to have an extra step ... used seldom
      \strc_lists_inject_yes[#settings,\c!type=\s!userdata][#userdata]%
    \else
      \strc_lists_inject_yes[\c!type=\s!userdata][#settings]%
    \fi}

\def\strc_lists_write_data_to_nop[#settings][#userdata]%
   {\endgroup}

\def\strc_lists_write_to[#tag]%
   {\begingroup
    \edef\currentlist{#tag}%
    \doifelse{\namedlistparameter{#tag}\c!state}\v!start
      \strc_lists_write_to_yes
      \strc_lists_write_to_nop}

\def\strc_lists_write_to_yes[#settings]#first#second% no \s!first 
because we don't expand user settings
 
{\strc_lists_inject_yes[\c!location=\v!here,#settings,\c!type=\s!simple][first={#first},second={#second}]}

\def\strc_lists_write_to_nop[#settings]#first#second%
   {\endgroup}
