source: src/AST/Print.cpp@ 2d6add4

Last change on this file since 2d6add4 was fca78f1, checked in by Andrew Beach <ajbeach@…>, 12 months ago

Added ForeachStmt (felt better than ForEachStmt). This new node is a bit optimistic in that currently it is covering a very narrow case, but with improvements to it and RangeExpr, it could handle many more kind of loops.
