<#
.SYNOPSIS
My Powershell profile
#>

# Halt on all errors
# By default, Powershell only halts execution on "terminating errors" (from `throw`)
# Setting $ErrorActionPreference to "Stop" will halt execution on "non-terminating errors"
# (from `write-error`) as well
$ErrorActionPreference = "Stop"

.SYNOPSIS
Re-source my profile
.NOTES
This can be called with '. p' (note the space), analogous to my '.b' bash function.
This function cannot exist in a module, due to scoping issues
