Can't read hdf5: io_hdf5.nim(17, 6) Error: 'parseNameAndGroup' can have side effects

[arkanoid87]

dump read_hdf5[float32]("res/myfile.nc", "/myds")

arraymancer-0.7.19/arraymancer/io/io_hdf5.nim(17, 6) Error: 'parseNameAndGroup' can have side effects
arraymancer-0.7.19/arraymancer/io/io_hdf5.nim(45, 36) Hint: 'parseNameAndGroup' calls `.sideEffect` '[]'

I've tried other read variants here, but all returned same error

Using nimhdf5 directly works without issues
