The only thing I really found weird syntactically when learning it was the single quote for lifetimes because it looks like it’s an unmatched character literal. Other than that it’s a pretty normal curly-braces language, & comes from C++, generic constraints look like plenty of other languages.

Of course the borrow checker and when you use lifetimes can be complex to learn, especially if you’re coming from GC-land, just the language syntax isn’t really that weird.
