Hi,
I find the new XeTeX primitives very very useful, especially \strcmp and
\ifincsname — thanks Jonathan!!!!!
I noted quite unexpectedly that nesting \csname…\endcsname, such as
\def\a{\ifincsname In csname \else Not in csname\fi}
\expandafter\string\csname
before nested csname:
\a
\expandafter\string\csname\space\endcsname
% ^^^^ it's a nested csname
\space\space\space\space\space
after nested csname:
\a
\endcsname
results in turning |\ifincsname| false: the example above typesets
\before nested csname: In csname \ after nested csname: Not in csname
Is it a bug or a feature? (I use nested csnames sometimes).
I use Ubuntu Lucid Lynx, TexLive 2009-7,
XeTeX Version 3.1415926-2.2-0.9995.2 (TeX Live 2009/Debian)
Best regards,
Grzegorz Murzynowski
