Merged my PR into Anchor v2 by @osec_io to add support for `Sysvar<SysvarInstructions>`.
This enables native Instruction Introspection for Anchor programs, removing the manual boilerplate previously required to inspect surrounding instructions.
A quick breakdown 👇🏼

Building from the island 🏝️
@rappanuiok from @SuperteamAR is shipping @usereflexmarket on Solana, an incentive layer for prediction markets.
Instruction Introspection allows a Solana program to inspect other instructions within the same transaction envelope.
Key use cases:
• Enforcing atomic multi-instruction execution
• Cross-instruction validation (e.g. CPI verification, MEV protection)

• Security checks without extra custom deserialization
With this change, `SysvarInstructions` can be passed and validated automatically directly in `Context` structs.
