Initializing global arrays in modules (i.e. outside functions), someone
mentioned this() as a solution:

<code>
module aepar_global;

const int MLdataNo = 13;
int[] metaData;

// Initializing Arrays (before main() is called)
this()
{
metaData.length = MLdataNo;
// or metaData.length = metaData.length + MLdataNo;
}
</code>

Alas this yields an error:

// aepar_global.d(115): constructor aepar_global.this constructors only are for
class definitions

And since

int[MLdataNo] metaData;

does not work either, I am a bit at loss what to do?

Its a simple mistake: you need to make the module constructor static.  Ie:

# static this() {
#   metaData.length = MLdataNo;
# }

The error message could be a little more helpful, I suppose.  Maybe by suggesting that what you seem to want is a 'static this()'.

Ah thanx... alas since it is not possible to search newsgroups, I was not able to find the initial post, that not doubt was correct.

To a certain extent, you can search the newsgroups: http://www.digitalmars.com/advancedsearch.html
