tiny alternative to std library

[Anthony via Digitalmars-d-learn]

Hello,

I noticed that importing some std libraries causes the build time 
to jump to around 1 - 3 secs.

I started creating my own helper functions to avoid importing std 
for scripting and prototyping in order to keep the compile time 
at around 0.5 secs.

I was wondering if anyone knows of any libraries that are geared 
towards something like this?

Thanks
