Summary
Fixes #9c06c3d5 (the issue about the last tuple sample being challenging for newcomers)
The F# Tour documentation included a code sample that used pattern matching/deconstruction syntax in function parameters without any prior introduction or explanation. Specifically, the sample showed:
This syntax
(struct(a, b))deconstructs a struct tuple in the function parameter, but readers encountering this for the first time might not understand what's happening, especially since the F# Tour is often one of the first pages people read when exploring F#.Changes
Added a brief explanation immediately after the struct tuple code sample that:
(struct(a, b))that appears in the codeImpact
This minimal change makes the F# Tour more accessible to beginners by providing context for advanced syntax when it's first encountered, while keeping the tour concise by referencing more detailed documentation rather than explaining everything inline.
