Re: Question: Applying a list of funcs to a list of expressions

In[1]:=

funcs = {f1,f2,f3,f4};
vals  = {val1,val2,val3,val4};

  Map[#[[1]][#[[2]]]&,Transpose[{funcs,vals}]]


Out[1]=

   {f1[val1],f2[val2],f3[val3],f4[val4]}

So, the "one liner" above will, I think, do what you want, but it's 
hardly eloquent, and far from transparant. I suspect that Mma has a 
cleaner build in function that, used appropriately, will do a cleaner job 
here.  I await the wisdom of the group.
