I'm trying to debug an expl3 code that usesl3seq and seq_gput_right. By adding the enable-debug and reviewing the code I get the error:

! LaTeX3 Error: Inconsistent local / global assignment

That was previously hidden (but worked fine). The error comes from the line seq_gput_right:cn, but if I change it to seq_put_right:cn the error disappears but the code does not work as it should.

The example file is the following, I have occupied it a lot of times and I had not noticed the error.

  Don't use seq_gput_right:Nn with a local variable (name beginning with l_). Global assignments must be done on global variables (name beginning with g_). By the way, it's quite strange to define a user command with _ in its name (like _appendcontents).

  OK, I understand about the use of l_ and g_, _appendcontents is an internal command, the user command is Scontents ( _appendcontents need double {{}}). The issue of changing the locale variables by global to disappear already cracked lists, edit the sample file a bit.
