Do you think it would be a good idea to let the user manually load NVM via a shell function?

Currently, NVM adds the following to your bashrc / zshrc:

[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

Those two lines cause a noticable delay every time you open the terminal.

Since a user probably isn't using NVM all the time (Only to install node once for most of us), what if instead those two lines were added in a shell function like this? :

function loadnvm
{
  [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
  [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion
}

With this, whenever I want to use nvm, I simply type "loadnvm" and then I could use the commands I need in that shell session.

You can add --no-use - ie, change [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" to [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" --no-use, and then it won't auto-use, which is the only slow part.
