Hi,

I tried something like this...
auto m = match("a=42 b=32 c=22", regex(`^(?: \s* (\w+)=(\d+) 
)+$`, `x`));

This works fine...
`^(?: \s* (\w+)=(\d+) )+$`
... and if I duplicate the string x times, it also works...

But I'm hoping to parse a variable number of these 'pairs'... so 
I tried grouping the pairs in (?:)+ but this way it saves only 
the last pair?

Anyone got an idea?

Then this foreach ought to save the day:
foreach( m; match(..., `\s* (\w+)=(\d+) `, `gx`))
{
	//some stuff with m[1] & m[2]
}

Throw in some experiment w.r.t. the end of line and you should be fine.

Bleh. Fixed:
foreach( m; match(..., regex(`\s* (\w+)=(\d+) `, `gx`)))


 {
 //some stuff with m[1] & m[2]
 }

Great, thanks for your quick support. :)

I actually did test `gx` but I failed to realise that I now have 
to iterate over matches as well as captures... which makes 
perfect sense when I pause to think about it.
