Writable constant indeed doesn’t make any sense, either in semantic or scoped variable. That’s why I prefer to disable it by default. Even Delphi had it disabled since Delphi 3, if my memory serves me right. However, this topic had been discussed over and over since a decade ago in FPC list but nothing changes. FPC still enables it by default both in Delphi and FPC mode.

Indeed, I don't see the point of static scoped variables.
But if you need those, then I'd rather see
var a : integer; static;
or something similar, than
a : Integer= 0;
Const should be exactly that, a const. My guess is that the original
"writable const" was simply a bug declared a feature.
