# astgen.zig: delay adding closure_capture instructions to preserve GenZir nesting\. Only containers create Namespaces, so the declaring_gz is always the GenZir passed to containerDecl, and containerDecl will always add exactly one instruction \(an extended \*\_decl\) to that GenZir\. Thus, closure_capture instructions are always lined up immediately after a container decl instruction, so rather than adding them at the point of first mention, where we're nested arbitrarily deep, simply walk through the Namespace captures hash map at the end of each containerDecl branch and add them then\. · gitcafe/zig
