Let in do-expressions

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
