From TypeScript 7's Go Rewrite to Go as an Agentic Language — The 10x faster, Go-powered TypeScript 7.0 compiler was released this week, and former Go product lead Steve Francia leans on Microsoft's success with the port to argue that Go is the natural default for agentic development.

Proposal: go run -c 'code here' — Some languages (like Python or Ruby) let you run once-off arbitrary bits of code as a one-liner from the terminal. Could Go do the same? Ian Lance Taylor, Rob Pike, and others weighed in on the idea in this golang-nuts thread.

Dan Kegel et al.

IN BRIEF:

• Go 1.27 Release Candidate 2 has been released.
• Go 1.26.5 and 1.25.12 have been released including two security fixes.
• The Go vulnerability database now marks golang.org/x/crypto/openpgp as unsafe, so govulncheck will start throwing warnings if you're using it.
• gopls 0.23.0 is the latest release of Go's official language server with fleshed out Go 1.27 support and an sqlrowserr analyzer that catches missing sql.Rows.Err() checks.

PROPOSAL UPDATES:

• maps.Same (formerly Identical) is coming to the standard library as a way to identify if two maps share the same underlying storage.
• x/net/http2's standalone Transport and Server types are now going to be deprecated (proposal accepted two days ago).
• sync/atomic may be gaining Max and Min operations (becoming a 'likely accept' two days ago).

Go Interfaces, Reflection, And Binary Size — As we learnt in Jesús Espino's deep dive into reflect, reflection keeps extra type metadata around, but it also stops the linker stripping unused methods.
