Indeed, however: ,,For input from a stream to return other than EOF 
after once returning EOF (with no intervening file-positioning 
operations or calls to clearerr) is non-conforming behavior, however 
widespread.'' (http://www.open-std.org/jtc1/sc22/wg14/www/docs/dr_141.html)

Is there any reasons for not putting ,,clearerr()'' in a front/back of 
,,luaL_loadfilex()'' as in ,,liolib.c:g_read()''? Certainly, when there 
is no ,,fopen()/fclose()'' used (i.e., when ,,stdin'' is used).
