Hi,

I am not able make use of these 3 special tokens to print something.

writefln("gshared: %s",__gshared);
writefln("thread: %s",__thread);
writefln("traits: %s",__traits);

------------------------------------------------------------
rc\Sample.d(128): expression expected, not '__gshared'
src\Sample.d(129): expression expected, not '__thread'
src\Sample.d(130): found ')' when expecting '('
src\Sample.d(130): __traits(identifier, args...) expected
src\Sample.d(132): found '}' when expecting ','
src\Sample.d(146): expression expected, not 'EOF'
src\Sample.d(146): found 'EOF' when expecting ','
src\Sample.d(146): expression expected, not 'EOF'
src\Sample.d(146): found 'EOF' when expecting ','
src\Sample.d(146): expression expected, not 'EOF'
------------------------------------------------------------

Would some like to show me how this is done??

They are keywords, so it's like writing:
writefln("traits: %s", for);

What do you want to do?

Looking at if they are run time related debug variables, perhaps consider using them within a logging api.

and what is the benefit over using libary functions?

how many of this special vars will come (and pollute the global namespace...)

google is your friend, search for "__traits d"

http://www.digitalmars.com/d/2.0/traits.html

I think __thread might be an alias for thread local. Maybe it was used explicitly in D1 since D1 didn't have TLS by default?
