Hello,
I found out that if you use the constructor function::function(unsigned
ser, const exprseq & es) to construct a function, this function does not
get evaluated if the exprseq was already evaluated. The reason is that the
expression sequence is copied with the exprseq::copy function and that
this takes over the status flags of the already-evaluated exprseq.
Therefore I think that the function
function::function(unsigned ser, const exprseq & es) : exprseq(es),
serial(ser)
{
tinfo_key = TINFO_function;
}
that occurs in the script function.pl should be changed into
function::function(unsigned ser, const exprseq & es) : exprseq(es),
serial(ser)
{
tinfo_key = TINFO_function;
flags = flags & ~status_flags::evaluated;
}
All the best,
Chris Dams
