So, why not allow capturing, since anyway the only place to capture are
constants and static variables?
Static variables already support arbitrary expressions since
https://wiki.php.net/rfc/arbitrary_static_variable_initializers. The RFC
initially mentioned static variables as a place where only const-expr
would be accepted, but I removed that once I remembered about that other
RFC.
And this way we could have short closures with auto-capture.
If there are some technical reasons for not doing that, can we have
written
in the RFC?
As stated in the RFC: This constraint is consistent with not supporting
variables in constant expressions. Capturing a variable is effectively
the same as reading a variable. It makes no sense to support one, but
not the other.
