Can I check I understand what you are saying here:

(1) If I create an app with 'pp --gui', and then run it by clicking the 
exe, I get my window app, without a console.

(2) At some point in my program I want to use print() to output a text 
string.

(2) I understand how, at that point, I can use AllocConsole(), along 
with a redirection of STDOUT to get the print()ed output to appear on a 
console.

(3) Now, say that I don't want to show the console when I create it - 
there is no way to achieve this with AllocConsole(), so I create the 
console, and immediately hide it, but get a console 'flash'.

You seen to be saying that I can use CreateProcess() to create a console 
that I can then redirect STD(IN|OUT|ERR) to in order to see my output. 
If so, then can you give me a bit more detail about the CreateProcess 
mechanism you use here.  I don't understand what I would pass as the 
CreateProcess() parameters to achieve this.

I intend that Win32::GUI::Console will have an "on-demand" mechanism to 
create a console when the first write to STD(OUT|ERR) happens.
