It did appear that implied multiplication was a problem. And IMO, it seems like implied multiplication on the Prime is a bit too aggressive and keeps sticking its nose in where it isn't wanted. It's really frustrating to keep unexpectedly running into what feels like arbitrary rules and restrictions in the parser and then having to waste time attempting to code around them, instead of simply being able to concentrate on the application I'm trying to write.

As a programmer, I am used to typing in the * whenever needed, and would be happy to turn off implicit multiplication. But if that were a configuration option (because I know many people like it) I would then expect {1, 2,3}2 to fail to compile because of the missing *. Having to type in {1,2,3}*2 would avoid it being mistaken for a list index.
To have {1, 2,3}2 sometimes read as a list index and sometimes as a multiply depending on a configuration setting would be just too confusing.
