💻 Code

const type = 'x'

type satisfies string // '=' expected.(1005)

🙁 Actual behavior

Gives an '=' expected.(1005) error.

🙂 Expected behavior

For it to work like with any other variable of any other name, specially since it's a common variable name.

Additional information about the issue

This also happens with other TypeScript keywords like interface.

If I wrap type in parenthesis it works, is this expected behaviour? The Deno formatter removes it (prettier handles it correctly), should I report this to them.

Start with the linked Playground reproduction and the parser path for satisfies expressions followed by identifiers that are TypeScript keywords, such as type and interface. Confirm the behavior against the shown snippet; done means these variable names parse like other names without TS1005 while preserving existing keyword syntax.
