For matlab, this would parse as

{ <the variable permut> <the first element of the variable permut> }

if permut was defined as a vector or matrix previously in the current 
variable space; or,

{ <the function permut without any arguements> <the function permut with 
the first arguement as 1> }

if permut was not defined as a variable in the current variable space.

I personally dislike the fact that matlab doesn't return an error when you 
use a function name on the LHS of an assignment; it often makes programs 
significantly harder to debug.  But, this is the way that matlab works, 
and we can't change it.
