Script Blocks Decoded
summary
Defines script blocks as anonymous functions and shows how they run via Invoke and the call operator, used in jobs and remoting with the using keyword and positional argument lists; demonstrates parameter validation limits (no parameter sets), builds dynamic modules in memory, creates a closure-based counter that preserves state, and assembles a proxy Out-Default that auto-cds or opens URLs. Demos include splitting by pairs, separable pipelines, and why module exports are closures.
