Expr: passing variables

if i use the simple expression: ‘a’ expr evaluates quite wrong, sometimes it takes the slice from the previous frame, which doesn’t exist anymore. not sure, which rules it’s following.
using ‘a*1’ instead works.

see patch

(yes this is a stupid expression, but it’s handy to apply calculations to just one component of vectors with a spread of expressions)
