Hi there,
I am trying to use the "let"-notation within do-expressions,
and it seems to me that it does not work correctly. (I am using
Hugs, version February 2000, on Solaris.)
E.g.,
do {x <- [1..9]; let i=1 in do {return ((+i) x)}}
works as expected, but with
do {x <- [1..9]; let i=1; return ((+i) x)}
I get:
ERROR: Syntax error in definition (unexpected symbol "i")
According to the Report (Section 3.14) the latter expression
should be a valid abbreviation of the former, or am I missing
something here? If it is a bug, has it been corrected in the
new version of Hugs?
Thanks,
Martin
