Once a function starts pushing 100+ lines, consider if it makes sense to start breaking up portions into smaller static functions.  Usually having another block of local variables declared in the middle of the function is a sign that a function can be made more modular.  This has the added benefit of reducing the lifetime of variables which results in reduced stack usage due to improvements in stack slot reuse.
