array := Array

You get:


array := {3+4. Date today}.

this does not apply to ObjectStudio

because ObjectStudio has already its own brace constructor for defining arrays which works differently and does not evaluate the expressions. The example code given results in ObjectStudio 8 in an array of six elements, two SmallIntegers and four Symbols: {3 #+ 4 #, #Date #today}

Loading the contributed parcel does not override this behaviour.
