Question: Inttrans invfourier(exp(-I*T*w),w,t) not calculated.

Using inttrans package fourier (Dirac(t-T),t,w) gives the correct answer

exp(-I*T*w).

Taking immediatel the inverse transform I get only

invfourier(exp(-I*T*w), w, t),

but the the expression remains unevaluated and cannot be brought to evaluate by any means that I know. Funny thing: Taking just plain Fourier Transform and Inverse in the usual integral form "int" it works flawlessly. Apparently Maple knows how to deal with distributions in this context. What am I doing wrong?
