746	invalidating blist entry for assignment not necessary when variable is not captured	felix winkelmann	felix winkelmann	"Assignment of lexical variables invalidates the ""blist"" entry, as an assignment may break type-assumptions when done (for example) inside a closure that captures the variable. The compiler marks captured variables so the invalidation may be unnecessary in this case. See comment in line 643 of `scrutinizer.scm`.
