@
has been reserved for new attribute syntax.
<<__Memoize>>
function life(): int { return 42; }
// Becomes
@__Memoize
function life(): int { return 42; }
The typechecker option disallow_silence
can be enabled to ban @
error suppression.
The typechecker option allow_new_attribute_syntax
can be enabled to allow @Attribute
support.
The runtime option hhvm.hack.lang.allow_new_attribute_syntax
can be enabled to enable @Attribute
support at runtime.
Hack OSS libs have typechecked with disallow_silence
enabled since November of 2019. It has not been mentioned on the blog yet, so private codebases may very well still contain a lot of @fopen(__FILE__)
code.
