Valid? print 1-2
stream(0, input, text, file("tabled_read_decl.data"))
1456

No such IO action.

test_2(stream(0, input, text, file("tabled_read_decl.data")), 1, 1456, _, _)
Valid? yes
Found incorrect contour:
test_2(stream(0, input, text, file("tabled_read_decl.data")), 1, 1456, _, _)
test(stream(0, input, text, file("tabled_read_decl.data")), 1456, _, _)
Is this a bug? yes
