Passing Deap Structure Table to Function 'Read-Text'.

Hi Expert,

I was passing a deep structure table to the function 'read-text' as 'LINES',  It seems working for cup of days ago, but yesterday I've hit an exception  for passing parameters with different structure to.

If passing deep structure to function is forbidden, why It won't come in the first place? 

Meanwhile, It will be greatful to explain, whatelse is forbidden for deep structure!

Thanks,
