The reason why it's bad is because you're encoding a mostly irrelevant
implementation detail in the interface to your program.

When you run "ls bar"; you don't care if ls was written in perl, python,
C, bash, haskell, go, or fortran. 

Things that live outside of PATH sometimes violate this practice. Often
in cases where the interface is constrained or the actual implementation
language is not an irrelevant detail.
