Bug 1578 – Allow AA literals to initialize static variables

const MTBit8 = 1; const MTBit16 = 2; const MTBit32 = 3; const MTBit64 = 4; const MTBit80 = 4; const MTBit128 = 5; static int sizemap[int]=[0:0,MTBit8:byte.sizeof, MTBit16:int.sizeof, MTBit32:8, MTBit64:long.sizeof, MTBit80:16];

This is documented, and hence an enhancement request: "An AssocArrayLiteral cannot be used to statically initialize anything." http://www.digitalmars.com/d/1.0/expression.html#AssocArrayLiteral

Reduced test case: static int sizemap[int]= [0:0, 1:1, 2:4, 3:8, 4:8, 4:16]; changed title from "const initializer rejected".

Came here from issue 6238 10.5 years and this is still a problem. Encountered when trying to assign AA literal to a struct member. See https://run.dlang.io/is/BDVjxP for another example.

The work-around is: enum int[int] sizemap= [0:0, 1:1, 2:4, 3:8, 4:8, 4:16]; BTW, this is a very old issue, if it's not intended to be fixed, can we add to the doc, and close it?

(In reply to mw from comment #6) > The work-around is: > > enum int[int] sizemap= [0:0, 1:1, 2:4, 3:8, 4:8, 4:16]; That's not a workaround *at all*. That's defining a constant. My example from 2018 even illustrates exactly this, and that assigning the constant to a static variable does not work.

This will be fixed in 2.106, we must have missed this one when merging the fix. https://github.com/dlang/dmd/pull/15468
