Applying a list of functions to a list of arguments

I have a list of functions, and a list of arguments:

For example,
f = {f1, f2, f3}
a = {a1,a2,a3}

I would like to return
{f1[a1],f2[a2],f3[a3]}

I thought this should easy, but am stumped. Obviously the lists are of 
equal, but arbitrary length, and the arguments may or may not be atomic 
expressions. In my particular case, the arguments are likely to be 
combinations of Real, and List[Real,...], but I hope this is 
irrelevant.

Any suggestions?

Many thanks,

Derek Yates
