Are there any known problems with the FORALL construct?

[Lahey Support]

Although there are no bugs in LF95's FORALL construct, it performs much slower than an equivalent DO construct. Since the FORALL actually performs more testing than the DO loop, one should expect it to execute more slowly. We hope to improve the performance of FORALL in future releases of LF95.
