i have written very large systems in labview, and your viewpoint is simply not accurate for a good labview programmer. just like any coding discipline, you keep your VIs, classes, libraries, etc. small and suited for a single purpose. what you end up with is a collection of VIs that basically have a REPL automatically built in (i.e., just run the VI). and when i say large systems, i mean multiple projects with greater than 1,000 VIs and many tens of classes.

it's a rule amongst good labview programmers that you keep your block diagram to where it fits on a single, reasonably sized/resolution monitor without scrolling. simply adhering to that rule encourages good coding practice. within my large systems, i am able to freely edit pieces with often no unintended consequences. since reference-based data types are really only used for multi-threaded communication and instrument/file communication, you typically are operating on value-based data which makes reliable code development quite easy.

and what you describe is equally applicable to any text-based language. neither labview nor text-based languages have built-in precautions against horrific coding standards.
