Leonardo Barbosa sent me the following 0.3K:

There's probably a way to combine the glob and the expansion that I don't know about, but you could do this:

  texs=(*.tex) && rm ${^texs:r}.aux

${texs:r} strips off the extension giving the Root name of each element in texs. The ${...}.aux causes the .aux to be appended, and the ${^...} causes the appending to happen element-wise.
