it relates to an indirect error: commands are of always expanded when 
you think they are, some are delayed; also, blank is handled partially 
in lua which then prints back stuff to tex which in turn can have an 
error in code you never see (so, line 8 is in some internal buffer with 
generated code)

in due time i can probably make error messages better but given the 
nature of the macro language it will never be 100% ok
