This has been stumping me:

   #!/bin/zsh -f
  =20
   echo $ZSH_VERSION=20
  =20
   x=3D$'\t\t\t'
  =20
   y=3D("${(ps:\t:)x}")
   echo $#y
  =20
   setopt rcexpandparam
   y=3D("${(ps:\t:)x}")
   echo $#y

This script prints:
   5.8.1
   2
   4

Why does rc_expand_param interacts with string splitting?

I know that if you use:

   y=3D("{(@ps:\t:)x}")

Then $#y is always 4, whatever rcexpandparams is set to.

Phil.
