DelayedArray crossprod with first vector argument doesn't work properly
library(DelayedArray)
x <- DelayedArray(matrix(rnorm(100), ncol=5))
crossprod(1:20, x)
## Error in base::crossprod(x, y) : non-conformable arguments
crossprod(1:20, as.matrix(x))
## [,1] [,2] [,3] [,4] [,5]
## [1,] -61.31712 -15.53516 27.05484 5.563496 -38.6093
Oops. It seems like

should have probably been a cbind, as that works:
crossprod(cbind(1:20), x)
