`PostfixNode
▪
The slot order is the mirror of : the operand comes first and the op descriptor second, matching the surface order of a postfix operator such as factorial .
x!
▪
op stays a language-native descriptor string (, ) rather than a Wolfram symbol.
"!"
"++"

PostfixNode
"Postfix"
▪
meta holds a position when the node comes from a real parse, and is an empty when you build it by hand - as in every example here.

x!
In[1]:=
 | PostfixNode |

Out[1]=
PostfixNode[LeafNode[Symbol,x,],!,]
In[2]:=
| ASTNodeQ |
 | PostfixNode |
 | LeafNode |
Out[2]=
True
