Hi,
the first:

open data9-3.gdt
matrix check = {1;2}
series x = (price > 3) ? check[1] : check[2] # fails

A 1x1 matrix apparently is not allowed here. (If I do 'scalar s = check[1]'
first, then it runs.)
True, it should. But let me add something quite off-topic. In my
experience, our "replace" function doen't get the popularity it deserves
IMO. Your example would become:
<hansl>
open data9-3.gdt
matrix check = {1;2}
series x = replace(price > 3, {1;0}, check)
</hansl>
which I find quite cool
The second "issue":
eval pi # works
Not sure if 'pi' is supposed to be an alias for '$pi'. For me
'pi' was a typo
and the fact that it didn't fail caused another bug that was a bit difficult
to track down.
That's a relic from the past. At some point we decided we'd deprecate the
dollar-less form, but never did in the end. Perhaps we now should.
