[parenscript-devel] 'Do' not working as expected

[Vladimir Sedach]

Hi David,

You want to use 'do*' instead of 'do'. Like in CL, 'do' does loop
variable initialization in parallel, so the initial value of i is not
visible when l is being initialized to (aref blorg i). 'do*'
initializes the variables sequentially.
