Use new abicoder pragma. 2020-11-23 18:06:44 +00:00			`pragma abicoder v2;`
Better error messages when writing to expressions that cannot be written to. 2019-08-12 15:06:10 +00:00			`contract C {`
			`struct S { uint256 x; }`
			`function f(S calldata s) external pure {`
			`s.x = 42;`
			`}`
			`}`
			`// ----`
Added error codes to SyntaxTest expectations (updated tests) 2020-06-19 00:26:46 +00:00			`// TypeError 4156: (128-131): Calldata structs are read-only.`
