+# Second semantic checking pass over the AST. Necessary because the old
+# way had some inherent problems. Performs:
+# 
+# * procvar checks
+# * effect tracking
+# * closure analysis
+# * checks for invalid usages of compiletime magics
+# * checks for invalid usages of PNimNode
+# * later: will do an escape analysis for closures at least
