Description
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.
